I completely agree with Annabeth and Percy. Even if you were successful in creating a basic infobox, you really don't want to work on it in the builder. Don't forget to ask for help at Portability wiki forums.

Also, bugs like this should be reported to Special:Contact/bug. It has probably been reported, but more reports will increase the priority on it getting fixed.
