>>Can anyone tell me why the following code used to work (under VFP50) and now, all of a sudden, gives me an error message "Operator/operandi mismatch" ? The underlying field is formatted for datetime and I haven't changed anything else (that I'm aware of) to cause this sudden refusal to work syndrome! Century is set on. Thanks in advance.

Does that mean that I need the Character to Date converter as in
IF !EMPTY(CTOT(This.value) < DATETIME() ???
I really need to validate this data.
