condition with toggle button (Access 2000)

[spiesser]

I have a function in my subform which works, but when i try to put a condition with the help of a toggle
button, it doesnt.I imagined that setting the true and false states of the toggle button i might trigger the
function but i cannot do it.Why is that?
For example my condition is :
If Parent!TglsET = False Then
FncCalc
End If

Where have you put this code? (I mean in which event procedure)
