Thanks for the response. This is more than likely me being daft but I've used the code you provided and set the labelFunction of checkData on the status DataGridColumn and I get an error in Flex stating: 1170: Function does not return a value. Is the checkData function checking both my customer and status columns for '2' or do I have to (as I expect) enter in the column name I want to check in the code you provided?
