Average Calculation Possible In LiveCycle?

Hello Adobe Fam,

I am new to LiveCycle and was wondering if average calcuation works in LiveiCycle at all?  I have a form that I built in Adobe Acrobat that works 100% and calculates dropdowns with no problem.  Manager is now requesting to allow comment boxes to expand as more text is added which i can't figure out in Adobe Acrobat but able to do in LiveCycle with no issue, but the actual average calculation is not workinag at all for the 8 dropdowns now but works 100% in Adobe Acrobat??  One thing this code does is excludes N/A from being counted in calcuation if selected.

Below is script that came over from the working PDF I built:

// Average non-N/A values;

var aFieldNames = new Array("Dropdown1", "Dropdown2","Dropdown3","Dropdown4","Dropdown5","Dropdown6","Dropdown 7","Dropdown8");

// counter for non-N/A values;

var nCount = 0;

// variable to sum non-N/A values;

var nSum = 0;

// default value for result if no average computed;

event.value = 0;

// process array of field names;

for(i = 0; i < aFieldNames.length; i++) {

if(this.getField(aFieldNames[i]).valueAsString != "N/A") {

// field does not have a value of "N/A";

nCount++; // increment counter

nSum += Number(this.getField(aFieldNames[i]).value); // add value to sum

} // end value not N/A;

} // end loop processing one field;

// compute the average;

if(nCount != 0) {

// non-zero divisor so we can compute the average;

event.value = nSum / nCount;

}

Thanks N advance for any help
