Try this code out.  It was used to see if the object was a checkbox and 
if the name of the checkbox matched "TermCode"  Put what you want into 
the condition.  All I did was record the element number into an array 
for future reference.

		for(var i = 0; i < document.forms[0].length; i++) {
		vType = document.forms[0].elements[i].type;
		vName = document.forms[0].elements[i].name;
		t = new String(vName);
			if((vType == 'checkbox') && (t.indexOf('TermCode') != -1)){
				// Append the form element index value to the end of the array
				aCBList[currentPos++] = i;
			}
		}
