Your question garnered very few replies which is often an indication that it wasn't well constructed. In this case using a literal string instead of the hash value would not only have made it clearer for us, but you'd actually have discovered the error an hour ago before you even submitted the question. A virtue of Perl Monks that has nothing to do with the community is that well asked questions often provide their own answer. :-)
