I have an ATL/COM project that I'm developing which have a number of functions that can be accessed in Excel as worksheets functions. All these functions so far belong to one object with the associated Interface. This all works great.
But when I added a second object and used the Tools-Add-ins-Automation to add it, its interface did not show up in the function categories and its functions are not accessible. The first object is visible and accessable though. Is there something I'm missing? or can excel only use 1 interface? ... Any help would be appreciated.

Thanks ...
