Thanks to both of you.

I have three workbooks open. I'd like to set an object to one of them so
I
can hide it away from the user, but still have it available for VBA to
write
to it. As far as I can tell, I have to use Application.Window, but I
can't
figure out how to set an object to one particular window to manipulate it.
Hints and suggestions are greatly appreciated.
