HTACCESS causing some problems

[eluser]codelearn[/eluser]
Hi guys,

I am trying to set up a mobile (m.cl.com) site.

HTACCESS File:

Code:

!^(index\.php|helpdesk|images|css|m)

I want to be able to put "m" into the redirect, without causing any of my controllers that start with "m" to 404. It's doing that now.

Thanks.
