Yes. CleanSheet is spelled correctly, I checked several times as I've
racked my brain on several occasions over something that turned out to
be spelling. As for how the module was developed, I created it in a
Workbook and I saved the workbook as an xla file. I didn't actually do
it in a module. I did try creating the menu and the procedure in a
workbook and used .OnAction = "ThisWorkbook.CleanSheet" And it worked.

Should I have originally coded this in a module?
