Presumably $errmsg is not appended to because empty($feedback) is FALSE. IOW
$feedback is not empty, IOW $feedback contains something. What I'm getting at
is when trying to debug some code, use a liberal dose of common-sense and
Print it out to see what it contains. Most likely it's whitespace. To convince
yourself that it does contain something use strlen().

What HTML code are you using to display the textarea field? Make sure there
are no spaces and/or newlines in there.
