Adding a menu item to Help

Can anybody see what I am doing wrong in this c# api?

int type = (int)(swDocTemplateTypes_e.swDocTemplateTypeNONE);

int helpMenu = m_oSldWorks.AddMenuItem4(type, m_oApiCookie, "About MyAPI...@&Help", 0, "DisplayAboutBox", "", "Information about MyApi", "MyApi.icons.aboutImage.bmp");

The menu item is not on the help menu.

Any help would be appriciated.

Thank you,

David
