how to add VBA forms to VSS

Hi,

I have Excel-VBA forms and modules. I want to add this project into VSS.

Steps to Add the project into VSS:-

1) Open Excel Application
2) Start the Visual Basic Editor(ALT+ F11) and Click Add Project to
SourceSafe.

My problem is I am not getting the menu as Add Project to SourceSafe. where
can I find this menu. I searched in google but I didnt get any solution.
somewhere it is mentioned we have to add vss into Add-Ins. How to add
Sourcesafe into Add-Ins. I am using Office 2003 and Visual Studio 6.0. Am I
missed anything during installation. Could anybody help to resolve this
immediately. It is very urgent.

Thanks in advance.
