Unable to Post this GI to the Customer Portal due to a missing entry screen error

I’m trying to publish this GI to the Customer Portal. It works on the main site, however, on the portal site it throws a error next to the entry screen under entry point: “A primary screen node for this inquiry form does not exist; it may have been moved or removed. Primary screen settings will be reset to default values.” Trying to View Inquiry results in a Error: “A site map node with the screen ID SO301000 does not exist. Maybe it was moved or removed.” Is there a way to get this GI to work?
