Robert,

One would think that a failure from a UDF would trigger an Error Routine based on a defined error number... therefore I would return a logical >after< the Error is triggered... seems to me a UDF which returns a 'value' by default would return, for instance, a '0' if the process failed for some logical reason (like trying to deduct an order item from an inventory when there is nothing in the inventory)... etc...

M2cents....
