If you open up Excel, record a new macro and run the other macro, what does it say? If you edit that macro and see what it says, then the ActiveX commands are fairly similar (though not always identical) to the code you'll see in the VBA macro in Excel. For example you may see something like
Application.Run "Book1!Macro1"
in the Excel macro. So the ActiveX command might be something like
Excel.Run('"Book1!Macro1"');
I don't know - I haven't tested this particular case but that's the process. You might go here for additional ActiveX help: http://msdn.microsoft.com/en-us/library/bb259457%28v=office.12%29.aspx
