Count checkboxes with 500+ unique names

Question

The form I am using a simple checklist, that was generated in Word and converted to a form in Acrobat, which is why it has so many unique field names.
I found the following solution but I am looking for something more elegant and that doesn't require me to enter each unique name.
I added the following script to the  document level function :
function CountCheckBoxes(aFieldNames) {
// count field names that have been selected
var count = 0;
var cField = "";
// loop through array of field names
for(i = 0; i < aFieldNames.length; i++) {
// for field names with a value of not Off increment counter
if(this.getField(aFieldNames[i]).value != "Off") count++;
} // end loop of field names
// return count
return count;
} // end CountCheckBoxes
I also added text field with the following custom calculation script:
// var define field names to be tested
var aFields = new Array('uniquename', 'anothername...etc');
// count field names that have been selected
event.value = CountCheckBoxes(aFields);
In order to quickly add 500+ field names, I use a temporary field to grab all the field value by using Pick under Calculate sum. I then cut and paste them into notepad and replace the
with
then a copy the full text into the above code replacing 'uniquename', 'anothername...etc'
It works but it is lengthy and I hoping a code guru might have a smarter solution.

That's the former, not the latter...
Anyway, you can use this code, then:
var totalCheckboxes = 0;
var totalChecked = 0;
for (var i=0; i<this.numFields; i++) {
    var f = this.getField(this.getNthFieldName(i));
    if (f==null) continue;
    if (f.type=="checkbox") {
        totalCheckboxes++;
        if (f.value!="Off") {
            totalChecked++;
At the end totalCheckBoxes will contain the total number of check-boxes in the file, and totalChecked the number of the checked boxes out of them.
