I need help on an template that is above two infoboxs and makes tabs between two infoboxes. The coding looks like this when being used: https://scoobydoomysteryincorporated.fandom.com/wiki/Crystal_Cove?action=edit

When I put the coding that matches the infobox, only the Original Timeline tab shows (which is the first infobox). What can I add to the template that makes it so I can use both tabs, only the first, or only the second one?
