How do I call an Excel Function (COMBIN) from my user created function?

I pass 4 variables to a VBA function, and from them calculate 8 dependent variables from which I need to calculate and pass back to the Excel cell:

FName = ( Combin(n1,n2) * Combin(n3,n4 ) +  ( Combin(n5,n6) * Combin(n7,n8 ) )

One by one I can return n1 - n8 and the numbers are correct, but I can't even get constants to work:  i.e.  FName  =  Combin(5,3)

Err: (With "Combin" hi-lited):   Compile error: Sub or Function not defined

Any help with syntax will be greatly appreciated.
