use strict and warnings. And don't nest your subroutines like that unless you know what you're doing and want to create closures on purpose. You might be using strict (I can't absolutely tell), but you're not using warnings, because you have a problem with that $key variable in the foreach loop not staying shared (its declared in a sub in an outer scope but being used in a sub in an inner scops).
