ActiveX button calling VBA from another hidden tab ?

Hey guys,

I'm currently reworking a xlsm file, almost from scratch (learned so many new things eversince I started posting here that I just had to do it). But before I do, I need to make sure of one thing; is it possible for an ActiveX button, placed on sheet1, to call a VBA procedure that is placed on a different hidden sheet (results of that VBA procedure are also posted on that same hidden sheet) ?

Just want to make sure to do the right thing before I get any further.

Thanks.
