I've created an Excel workbook with several userforms and macros, and need it
to run on a Mac running Excel X. When I open the workbook in Excel X on the
Mac, and open the VBA Editor, none of my forms show up - as if the VBA
project contained no userforms at all - and executing the code to load and
show the forms causes an error.

I've read that the Mac version of Excel doesn't support ActiveX controls.
My question is: is there a way to build a userform in Excel VBA (in Windows)
using controls that aren't ActiveX controls? Or is ActiveX all there is for
building userforms in Excel VBA? I've seen people say to use the controls
from the Forms toolbar in Excel, but I don't want to add controls to the
workbook, I want to add them to a userform (if this makes any sense).

Thanks
