I'm trying to use master pages...and am probably doing something wrong - so please help...

Here's what I've got - I have a BO project and my main project.  When trying to add a new form based on a master page - here's what I'm doing:

1. right clock on main project

2. select add then new item

3. select SF Web Form w/Master - click add

4. the wizard then appears to look only in the BO project for the master page - if I delete the BO project, it looks in the main project.

So, what am I doing wrong???  How do I keep both projects and have it look in the main project for the master page - or - do I have to put the master page in the BO project?

Thanks again - HB
