How to subtract in a calculation in Acrobat Pro 9

[_sander_wessel_]

I'm building a pdf with some calculations. I can do a 'sum, product,average,minimum,maximum'. But how do i subtract 2 fields?

You will need to use JavaScript in a field's custom calculation script. For example:

// Get first field value

var v1 = getField("Text1").value;



// Get second field value

var v2 = getField("Text2").value;



// Set this field value equal to the difference

event.value = v1 - v2;

You would replace "Text1" and "Text2" with the names of the fields you've set up.

I guess I'm missing something. I can't get this to work. Here is the script that I am using.

v1 = getField("Subtotal").value;
v2 = getField("TotalDiscount").value;
TotalDue.value = v1 - v2;

Any help would be appreciated.

Use this:

event.value = v1 - v2;

I used George's suggestions with Bernd's alteration, and it worked great for me. Thanks!

I should not have said you *need* to use JavaScript, because you can also use the "simplified field notation" option, but as you come to do more than the simplest of calculations, JavaScript is what you'll need.

If you want to use the simplified field notation option, you'd enter:

Text1 - Text2

but you'd replace Text1 and Text2 above with the names of your fields.

I was unable to subtract using the guidance you provided. Do I need to add an equal sign or something?

How would you write this if you were wanting to subtract dates? I'm using Acrobat 9 as well. Thank you!
