# Special Formatting after Simple Calculation

I've got a set form field that each asks for a numbers, does some math, and displays the results in a separate field.

What I'd like it to do is simply add together all the inputs (not a problem) but then take the result and modify them as follows: If you can subtract 5 from the result and still get a positive real number, it also displays those number after it.

For example:

Input 4

Output w/formatting: +4

Input: 8

Output w/formatting: +8/+3

Input: 5, 3, 6, 7

Output w/formatting: +21/+16/+11/+6/+1

I'm beat after a days worth of syncing up fields, if someone could lob this one over the plate for me, I'd really appreciate it.

You can use the following as the custom Format script of the Total field, but you owe me a six-pack.

(function () {

// do nothing if field is blank

if (!event.value) return;

// get field value as a number

var num = +event.value;

var d = 5;          // divisor

var s = "+" + num;  // begin building output string

var it;             // number of iterations

// determine remainder

var r = num % d;

// if remainer is not less than divisor...

if (r !== num) {

// determine number of iterations

it = (num - r) / d;

// build up output string

for (var i = 0; i < it; i += 1) {

s += "/+" + (num - (d * (i + 1)));

}

}

// display output string

event.value = s;

})();

This code is based on the assumption that the input is a positive integer. If you don't already enforce that with a Keystroke/Validate script on this or other fields that this field value is based upon, you should.

If you don't already enforce, you should

Done, and also that worked perfectly. Gotta love the people on Adobe forums, first rounds on me!
