Is it possible to use the update trigger for a table to update fields in the table that has fired the trigger.

What I would like to achieve is to have the Update Trigger set a date and time field with the date & time that the record was updated. If I try to do this using the following procedure I get an error message "cannot update the cursor".

PROCEDURE _TESTTABLEUPDATE
IF _TRIGGERLEVEL > 1
RETURN .t.
ELSE
REPLACE DATE WITH DATE() IN TESTTABLE
REPLACE TIME WITH TIME() IN TESTTABLE
ENDIF
RETURN .t.


Any advice gratefully received,

TIA

Andy
