@christopher.amirian Thanks for the alternative method. I wish you would have been the first one to reply on this thread, it would have saved 9 days of back and forth, often repeating the same issues.
Unfortunately I can’t hand this type of setup over to the client… having them edit global blocks, or assign a new header, seems like there’s too much room for error.
I think the only reasonable option at this point is to hire a developer.
