Hi

I have taken your advise and have now not used the a & b procedures
and now switch from one userform to another and i have found that when
i switch they do not unload from the memory stack and after a while i
still get the error 28.

Is there a way of stopping the buildup in the memory or am i asking to
much?

thanks
