Get Data from a Single Radio button with Javascript

Auto-generated radio buttons cause a special case where one radio button may be created. Reading back a single radio button is different to reading from a group of radio buttons.

Take a radio button(s) called quoteList?where the value is an integer:

 	if (isNaN(frmData.quoteList.length)){		// branch required because radio button handling is different for single row lists		//(no element array for singles)		if (frmData.quoteList.checked){			intID = frmData.quoteList.value;		}	}	else{		// get which policy is selected		for(intCounter=1;intCounter <= frmData.quoteList.length;intCounter++){			if (frmData.quoteList[intCounter-1].checked) {				intID = frmData.quoteList[intCounter-1].value;			}		}	}
