Getting strange output on commands that used to work

I have used the following code before and it worked then but now it seems to default to the word Function, and some of the other commands are giving results like All when they used to work.

Would you help clarify what’s going on?

 usaStateCases[s_] :=       Select[data, MatchQ[Interpreter["USState"][s], First[#]] &][         All, #ConfirmedCases["LastValue"] &] // Normal // First          usaStateDeaths[s_] :=       Select[data, MatchQ[Interpreter["USState"][s], First[#]] &][         All, #Deaths["LastValue"] &] // Normal // First          usaStateCases["California"]  

This used to work but now, the output of the last line is Function

TIA
