Calculation resulting from checkbox selection in pdf

[sasegars58]

I'm probably way out of my league here, but here's what I need to happen:

I have a fillable pdf with several checkboxes that would result in an amount being added to a total field (Ex: Full page ad / Exhibitor fee is $500 / Non exhibitor fee is $750), so the user selects two items (or none). If they check "Full page ad" checkbox, then they select whether or not they are an exhibitor, then the amount ($500) would go to the total field = $500. And several more optional add choices, etc.

So, I guess my question(s) are:

If a checkbox is selected, can a number populate in a separate field? And if so, how?

I am a javascript beginner, have only completed the calculations that were simple.

Many thanks in advance for help/advice.

I have a similar issue... this is the code im trying to use, Im trying to get a check box in adobe to (When checked) to subtract "TTLCalculated" And use that value in the next part of my code, wanted to know if what im doing wrong, im a newbie to javascript, would really appreciate the help!

var DA = Number(this.getField("Downpayment*").valueAsString);

var DA2 = Number(this.getField("TTLCalculated").valueAsString);

event.value = (DA-DA2);

if (this.getField("TTLCalculated").value!="Off") event.value=(DA-DA2);

else if (this.getField("TTLCalculated").value!="Off") event.value=0;

YOu have exactly the same condition in both parts of the if block. Remove the second if. Just use an else.

Hello,

I am trying to do something similar. I have a specific rate that gets calculated on top of the total amount. However, the payment type changes the rate.

At the moment All payment types has a rate of 8.42% added to the total amount which is annotated in the G&A (named 5 on the PDF) i have added using the simplified filed notation which is TOTAL_COST * 0.0842, this will happen regardless the payment type. However, for three payment types its 7.67% added cost and one is 9.55% added cost. How do I have the specific rate calculation work with the specific payment type selected?
