Hello, I'm Helen Bradley.
Welcome to this video tutorial.
In this tutorial we're going to have a look at creating spin buttons in Excel to make
data entry just about as much fun as data entry can be.
Before we get started with spinner controls let's have a look and see what we're talking
about.
Here is a copy of the worksheet that we're going to be working on and this is the spin
button control.
It's been set to work between 20 and 30 so it will take a value between 20 and 30 years
and every time I click the down arrow it decrements this cell by one so that the overall payment
per month on the mortgage is increased because the term is much shorter.
When we increase the term on the mortgage by clicking on the up arrow the overall payment
is reduced.
And it stops at 30.
So let's see how we would add the spinner control to this particular worksheet.
Well first of all you have to have the Developer tab available.
It it's not choose File and then Options and in Excel 2013 and 2010 you'll go to the Customize
Ribbon button here and you'll check this Developer tab here so that turns it on.
In Excel 2007 you'll go here because there will be an option here for Show the Developer
Toolbar in the Ribbon.
So once you've got the Developer toolbar available click it and then take this Insert option
and you want the form controls.
Now the Active X controls look pretty much the same thing but they work very, very differently.
And what we want are the simple form controls because they're the easiest to use.
I'm going to click here on the spin button control and then I'm going to click and drag
to create the control on my worksheet.
Now I can resize it later on but I'm going to start by drawing this size.
I'm now going to right click it and choose Format Control.
And this gives me my options for formatting the control.
To start off with I can set its current value.
So I can start it at for example 25 and then I can set its minimum value which I had previously
set to 20 so all our mortgages are going to tested between 20 and 30 years in length.
And then I'm going to make the maximum value the 30.
So we're going to move between 20 and 30.
And the incremental changes how big a change do I want to happen with each click of the
button.
Now these have to be integers so one is the smallest value.
And cell link is a pointer to the cell that I want the value to be inserted in so I'm
going to click in here and then click in this cell because this is going to be my link cell
and click Ok.
You can see that the cell value changed to 25.
That's because that was the starting value.
Now if I click on the spin button right now nothing is going to happen because it's still
active.
So I'm just going to click outside it and now I can test it.
You can see I can click up but when I get to 30 I can't click it any more and then it
will click down.
And when I get to 20 it won't go any lower.
So that's a spin button control that you can use to control this sort of value.
But there are some limits to spin buttons that we're going to have to get around.
One of them is that they only return integer values and the maximum value is 30,000.
So right now that would cause us some problems in trying to add the mortgage amount which
is in the region of 200,000 or more when the maximum value is 30,000.
And here the interest rate is 5 percent.
That's .05.
That's not even an integer.
It's not even a one.
So we're going to have problems controlling that.
And we're going to have to find a way around it which of course can be done easily.
To see how we would deal with the situation where the amount borrowed is a much larger
figure than we can use in the spin button control let's have a look at this worksheet.
In this worksheet we're looking at how we could possibly scale a range of 0 to 30,000
to actually work for us.
Let's say that the minimum amount that we want this mortgage calculator to work for
is 100,000 and the maximum is one million.
Well let's look and see what 100,000 is.
Well 100,000 is 10 times 10,000 and a million is 100 times 10,000.
So we could have our spinner work between 10 and 100 if we could scale it up by 10,000
each time.
I'm going to replace the formula with a value and it's going to multiply the contents of
cell D2 by 10,000.
Now there's nothing in cell D2 right now but we know that we can put a value in there using
a spin button.
So again Developer, I'm going to Insert and I'm going to select the Spin Button Form Control.
I'm going to drag to create it on the worksheet, right click it and choose Format Control.
This time I want my minimum value to be 10 because I'm going to use a 10 to 100 scale
here.
The maximum value is going to be 100 and I'll have it increment by one digit at a time which
is going to be 10,000.
I'm going to set my current value to, for argument sake, 20 so that we'll get back our
200,000 in this cell.
And the cell link cell is going to be the cell that has the value in it that this formula
is using.
When I click Ok let's see how it's working.
As you can see the spin button here is giving us this value here of 20 and in this cell
we're just taking the value of 20 and scaling it up.
So now if I click on this button it's going up by 10,000 every click of the button and
it's going to max out at one million.
And if I were to come down then it would max out in the bottom direction at 100,000.
And each time as I click on the button, well I'm sitting on the button right now, but as
I click on the button the amount that we're paying each month is being recalculated accordingly.
So scaling up like this is a way of getting larger values than the 30,000 that we're allowed
in the spin button control.
Of course that's preempting the solution for this value here.
All we need to do now is to scale this downwards.
So let's see how we do that.
To reduce a value using a spinner we'll work the opposite direction.
Let's say that we want an interest value between 2 and 10 percent.
That's between .02 and .1. .02 can be represented by 2 times .01 and
10 by 10 by .01.
Now that's only going to give us whole interest values so I don't think it's going to be quite
big enough.
Let's go down a scale and let's say it's 20 multiplied by .001 and 100 multiplied by .001.
That's going to give us additional percentages in the range so instead of going 2 percent,
3 percent, 4 percent we can go 2.1, 2.2, 2.3 and so on.
So let's take this scaling back to our worksheet.
Again we're going to add a spin button here so from the Developer toolbar Insert make
sure that you're using this form control and drag a spinner into position.
We'll right click it and choose Format Control and we're going to use cell D3 as our intermediate
cell.
The minimum value is going to be 20.
The maximum value from our previous calculations on the other worksheet is 100.
We'll use an incremental change of one for now and the cell link will be this cell here
D3 and press Ok.
Now nothing is actually happening because we haven't put our formula in here yet.
The formula multiplies this value here by .001.
And here is our smallest value 2 percent.
We'll need to reformat this cell so I'm going to the Home tab of the Ribbon and I'm going
to increase the decimal places here so that we can see exactly what values we're getting
and not rounded values.
Here everything is now going up in .1 of a percent.
And it will max out at 10 percent because that's where we set it to max out at.
It won't be able to go any larger than that.
Now all we need to do to make this worksheet a little bit neater is just to hide the column
that contains those intermediary values.
And now somebody can use this calculator to calculate a loan and instead of having to
put value in here manually they can just click on the spin button controls to do it automatically.
