I know how to code for controls placed on a sheet, both form controls and ActiveX.

And I know how to create and code for a UserForm.

But here is where I am having a problem:

I have inserted a Microsoft Form 2.0 Frame onto an Excel Sheet. On that form, I have placed a Command Button.
I cannot find how to code for the click event of that button. The same is true for any other controls placed on the form frame.

I can view code for the frame and write code for that, e.g. clicking on the frame itself.

But when I try to view code for any control on the form, that option is greyed out.

What do I need to do for my code to reach the controls on a Form 2.0 Frame?
