Automating a Word Macro from C# - CSharp

Hello,

I am trying to run a Word Macro from C#. I am getting the error:

Unknown name. (Exception from HRESULT: 0x80020006
(DISP_E_UNKNOWNNAME))

when I get to the line that actually runs the macro. All the other
code runs correctly. Am I calling the macro correctly? The macro is
available in the Normal.dot template. It is available if I open the
file and manually try to run the macro. It just fails when I try to
automate it.

I have attached a code snippet. Any help is appreciated.

Thanks,
Fatima
