Custom calculations in an interactive PDF scale/checklist?

Question

Hello community!

I am looking to achieve a few custom calculations within a interactive PDF scale/checklist.

I've attached an annotated image attached to better explain the type of calculations I'm looking to do, but here is a written summary too:

1.) Have a specific field sum the # of checkboxes that have been checked in the same column (ie: if 2 of 4 checkboxes have been checked, the sum field would populate with the number 2)

2.) Have a field show the results of the sum of a different field multiplied by a specific value (ie: Sum of "Field A" x 2 = "Field B")

Any help would be greatly apreciated!

Thank you 🙂

Ah! Now I see what I was doing wrong with the checkboxes. I have got that to work!

However, now I can't seem to get the highlighted field "6.Never" (in blue) to populate with x2 of the value that will appear in the field above entitled "5.Never" (which currently populates with however many of the checkmarks are selected). Does it look like I've got the calculation right? I've included a screenshot below.

Thank you again for all your expertise here!

Simplified field notation doesn't work well with names with dots, spaces...etc give your field a simpler name like "Never" or use this script under 'Custom calculation script':

var f = Number(this.getField("5.Never").valueAsString);
if(f!=0)
event.value = f*2;
else
event.value = "";

1. Just give each checkbox an export value of 1 and under 'Calculate' tab select 'Value is the' and pick checkboxes.

2. If the number is entered into the field, you can also use the built-in calculation.
