I am creating child content type "CSASurveyAnswer_2_ControlStatements_ZugHQ", under the parent conten type "CSASurevAnswer" from sharepoint UI. And the parent content type "CSASurevAnswer" has already the other three child content types: "CSASurveyAnswer_1_ControlStatements","CSASurveyAnswer_2_Healthcare"&"CSASurveyAnswer_2_Finance" while creating the above child content type"CSASurveyAnswer_2_ControlStatements_ZugHQ" it's giving me an error "a duplicate name already exists". If we open the site in designer, the same content type "........_ZugHQ" is appearing under the _cts folder. But not under the galleries of site content type. how shud i go ahead and create new child content types.

Hi SridharS, What if you delete the “_ZugHQ” folder under _cts in SharePoint Designer and try again? Thanks & Regards.Lily Wu
