davidj has asked for the
wisdom of the Perl Monks concerning the following question:
I have been scratching my head over this trying to figure out what I am doing wrong. For the life of me, I am not seeing it. I am using grep to test the value of a query paramater. The value IS in the list, but grep is not finding it. I hope I have included all the relevant information below.
