im using access 2007,
i have a sub form with fields "A" and "B" on it.
i want that after each change of value of "A", "B" will recivethe new value of "A".
i managed doing it by writing a simple code, but i wish to know if there's a way to do so using the "Expression builder"?
i tried what to me seemed the obvious way:
after update of A : [B]=[A]
but thats not working.
is there a way?
