Daniel,
I appreciate your help. I got drifted away yesterday and got back to it
today. I found my mistake: a fricking typo. My polls/detail.html look for
'error_message' while I spelt 'error_messge' in my views.py. So the error
msg was never shown though the page was redirected properly.
Thanks again!
