Nicpetbio23!:

You don't reference a hash from the values, but from the keys. So $ret{$value1} isn't going to give you what you want. You really need something like $ret{$key1} to get value 1. So you probably want to create a reversed hash:

my %reversed_ret = (reverse %ret);

Then you can check for $reversed_ret{$value1}. Note: there's a problem with reversing a hash like this: If you have the same value1 for multiple keys, then that value will return only the last key you added to the reversed hash.
