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.

Edit:  fixed typo

Nice job, it looks good. Just a few suggestions:

1. Make all of the % cleared fields and the total  fields at the bottom to read-only

2. Make all of the actual number and number cleared fields formatted to show no digits to the right of the decimal.

3. Set the tab order. It will be easiest to just set it to row order, as opposed to manual.
