----------------
You don't seem to be using the [[TGI]] variable you captured here, did you intend to?
Possibly related, I assume you meant to check that the TGI variable is of type TGIT? (I don't believe that's strictly necessary - sort of 'belt and bracers', but not wrong either - we've checked that template types can be correctly associated with variables of that type, we could just say that we're assuming that's correct here & only test the template type)
