project Add menu group

Hi  experts!!

I'm try to add a context menu into project's Add group , but it doesn't show up.

Following is what I defined in .ctc file

In NewGroups


 NEWGROUPS_BEGIN
  // NewGroup                              Parent Group                            Priority
  guidVsMyMenusCmdSet:MyMenuGroup,    guidSHLMainMenu:IDG_VS_CTXT_PROJECT_ADD,    0x0002;

  NEWGROUPS_END


in buttons section


 BUTTONS_BEGIN
  // Command                    Parent Group                Priority    Image            Type    Visibility       
  guidVsMyMenusCmdSet:cmdidDeployPackageEditorMenu, 
  guidVsMyMenusCmdSet:MyMenuGroup,
                                0x0100,
  guidVsMyMenusCmdSet:bmpPic1,
                                BUTTON,
                                DYNAMICVISIBILITY ,
                                " My New Item";
  BUTTONS_END


I'm wondering what's wrong here. I'd appreciate any help
