That is very broken. If a value appears more than once in the two hashes, then your code will discard all but one of the keys it is associated with. You can't just invert the hashes unless you know that all of the values are unique (or you don't care about losing data.)

Update: I was wrong. As jdporter explains below, he is not using values as keys. My apologies.
