try{
fieldCol.text = dataArr[0].FieldName;
}catch(e:Error){}
Yes, I know the field name but I keep getting range error and I know the value
is there. but even when it isn't how do I trap the error when the value
requested returns an array of zero elements?
Thanks for the help.

The exact error is...
RangeError: Index '0' specified is out of bounds.
