Hi!

Thanks for fixing me.
I guess you can try to use a view and refresh() for it before saving. Refresh for current record in view do not affect changed values, however, it updates the values returned by CurVal(). Anyway, you cn try this and see of this fix the OldVal returning.
Finally, for new records OldVal() will return NULL. If you check for Field<>oldval(field), it is incorrect because if Oldval() returns null, the comparison will be .F. (means equal that is not correct). Check if you did nto missed the issue with NULL returned by OldVal().

HTH.
