What the Heck?

Okay, so in a past project I had used IDL to expose a UDT i had in a dll to an excel spreadsheet. The DLL in that case was a straight C++ DLL, no MFC. In this case I have an MFC DLL. I want to expose a UDT to the excel spreadsheet. I have tried, but it does not work. I have the UDT defined in my IDL file, but when I use "references" tool in excel, I dont have access to the type? The code is below. Am I doing something wrong here?
