I can add any project to any project suite... that's supported just fine. What you're doing is correct... but you need to understand that the "add existing item" is adding a file. So, the keyword test you want to add is a file located on the hard drive, probably in a default location according to the project in which you ORIGINALLY created it. So, to add it, you'll need to browse to it in order to select it.
Keep in mind... a Project Suite is not like an "application"... adding a project to a project suite does not automatically give all projects in the suite access to the same information. The Project is the primary, the suite just organizes projects.
Thanks for your reply, Robert.
Mathijs, is your question resolved? If so, do you mind accepting Robert's reply as a Solution or posting your own?
