I'm assuming you've got problems with this line: `%newHash .= \%valueHash;` [download] I'm very surprised that didn't throw a syntax error. .= is the string concatenation operator. You can't just use it to combine hashes. You'll want something like: `@newHash{keys %valueHash} = values %valueHash;` [download] Which inserts the key-value pairs in %valueHash into %newHash, overriding any pairs with the same names. Side note: if you're having trouble with some almost totally unrelated problem, it's probably better to post a new, trimmed-down version of the new problem instead of updating an old one.
