Oh! Yes, changing the variable name in the subroutine 'breaks' it as expected
To avoid wasting time chasing silly mistakes like these in future, I suggest you always -- as a matter of routine habit -- order your file with functions first and mainline at the end.

An alternative is to leave the mainline first but put a bare block around it, to ensure mainline global variables don't accidentally leak into the subroutines defined below.
