calculation help - (Q1*$1)-(DISC1/100) and SUB is empty IF 0

[victoriap31769655]

Attached is a link to the photos of my invoice form. I have the following columns:

Q=QTY.

$=$

DISC1=DISCT.

SUB=SUBTOTAL

I would like the subtotal to accurately calculate from the corresponding row values. Essentially the calculation of (Q1*$1)-(DISC1/100) so that the discount column presents as 35% instead of .35 when I present it to clients.

Then, how do I code SUBTOTAL as empty when the corresponding rows are empty.

This is a good starting point for this task: https://acrobatusers.com/tutorials/how-to-do-not-so-simple-form-calculations

I found that article on my search before posting, but I need a custom calculation script in order to get the SUB=empty if Q,$,and DISC are empty

You need a simple if-condition. See: https://acrobatusers.com/tutorials/conditional-execution

thank you! those articles in conjuction were perfect for my puzzle. I ended up with this:

event.value = (this.getField('Q1').value && this.getField('$1').value && this.getField('DISC1').value) ? ((this.getField('Q1').value*this.getField('$1').value)-(this.getField('DISC1').value/100)) : "";

Well done!

It is best not to ask "how to code" because it can be seen as just asking us to write your code for you. Most of us are more interested in giving you what you need to learn how to write your own.

I did take the articles that try67 sent to me, as per my request on "how to code" and I came up with a code that works perfectly

event.value = (this.getField('Q1').value && this.getField('$1').value && this.getField('DISC1').value) ? ((this.getField('Q1').value*this.getField('$1').value)-(this.getField('DISC1').value/100)) : "";

you've misinterpreted my intentions. I love finding the "why" behind the code, not just the "how"

[victoriap31769655]

not just the "what"**

excuse the typo! and thank you again for suggestions!
