i'm obviously not understanding? You have an existing menu created in XL2003. This will appear in XL2007 on the add-in tab. (by default, there is nowhere else it can display).
The ribbon you have created in XL2007 is a seperate object. You cannot merge the two it is one or the other.
If you wanted to replicate the button that is on your ribbon onto the commandbar on the add-ins tab, just go back to Excel 2003, write the extra code and that too will appear on the add-ins tab with the other 'old' controls.
