Desperate for help to create a script!

Question

I know nothing about scripting, but I'm hoping Acrobat has a script that would work to calculate the percentage of two numbers in form fields. I work for a police dept. and need to calculate the percentage of crimes solved vs. crimes committed (ex: 5 robberies, 2 of these are solved, so I need the third form field to calculate the solved percentage of the crimes). Can anyone SAVE me, please?

Here's a custom calculate script you can use for the % cleared field. It assumes the actual number field is named "an.1" and the offenses cleared field is named "oc.1". It sets the value to "0.0%" if either of the input is zero or blank, which you might want to change to something else like an empty string ("").
// Custom Calculate script for "% Cleared" field
(function () {
    // Get the values of the inputs, as numbers
    var actual_number = +getField("an.1").value;
    var offenses_cleared = +getField("oc.1").value;
    // Set this field's value. Round to 1 decimal point and add % sign
    if (actual_number !== 0) {
        event.value = util.printf("%.1f", offenses_cleared / actual_number * 100) + "%";
    } else {
        event.value = "0.0%";
Since it sounds like you will want to be doing the same calculation for several rows, this really should be made into a document-level function that can be called by all of the % cleared fields. If you continue the field naming scheme and named the fields in the rows like "an.2", "oc.2", "an.3", "oc.3". etc. the function could be:
// Function in a document-level JavaScript
function percent_cleared() {
    // Get the terminal field number of the field that called this function
    var fn = event.target.name.split(".")[1];
    // Get the values of the inputs, as numbers
    var actual_number = +getField("an." + fn).value;
    var offenses_cleared = +getField("oc." + fn).value;
    if (actual_number !== 0) {
        event.value = util.printf("%.1f", offenses_cleared / actual_number * 100) + "%";
    } else {
        event.value = "0.0%";
and then called it like this in the calculate event of each "% cleared" field:
// Custom Calculate script
percent_cleared();
If you're unfamiliar with creating document-level JavaScripts, post again.
