301 redirects for multi-variable ASP URLs

[lightgirl]

I have tried repeatedly to set 301 redirects for this particular old URL and I just can't get anything to work. If anyone enjoys solving these rewrite puzzles, I would be grateful for any help.

http://www.example.com/subdir/anmviewer.asp?a=7&z=2 which should redirect to: http://www.example.com/april-20-2004

I have tried:
RewriteEngine On
RewriteCond %{QUERY_STRING} ^a=78&z=2$ [NC]
RewriteRule subdir/anmviewer.asp http://www.example.com/april-20-2004/? [R=301,L]

But it fails. Can anyone detect what I'm doing wrong?

Thanks in advance for any help.

Typo when posting, or actual typo in code?

Oh mercy, it was a dumb typo in the code. I corrected htaccess entry and now it works fine. Thanks very much for catching my error, and sorry for the bother.
