Hi Steve,
It looks like you're trying to develop a solution using Microsoft Word 9.0.
You may want to post this message in one of the Word newsgroups (like
microsoft.public.word.programming). This newsgroup is designed for people
having trouble with the Visual Studio Tools for Office product. (Please
see http://msdn.microsoft.com/vstudio/office/ for more information
regarding Visual Studio Tools for Office.)
