Codas and Fine's not working

Hiya. I'm writing a part out from Ohio State's fight song, "Across The Field" and they have what they call a tag ending which happens at the very end (hence "tag".) I have done exactly what is shown in the original part, though anything after the coda in my score (where the tag is) literally doesnt play. it doesn't allow me to play, if i try to it goes back to the start after fighting it. I'm quite confused.
Below is the MS file for the part, and the original part can be found at https://tbdbithttps://tbdbitl.osu.edu/sites/default/files/2023-05/osumb…-02-_solo_1st_trumpet_in_bb.pdf on the second page, titled "Fight the Team (Across the Field) with OHIO tag".
Cheers!
