When I do a ExecuteSQL () I am getting "There is an error in the syntax of the query." with in the data viewer.
but when I attempt to change the Expression with in the data viewer Filemaker crashes.
ExecuteSQL ( "SELECT d__NameLast FROM @User WHERE d__NameFirst = ?" ; "" ; "" ; @User::d__NameFirst )
