如何在非索引页面上创建漂亮的URL?

I'm sorry for making you guys spin your heads off for me. This is my situation: In my htdocs folder, I have a folder called mediaschedulesgh. In mediaschedulesgh, I have all the web files. so, it is my root folder. the index.php, ghana-radio-stations.php and .htaccess are in mediaschedulesgh with other folders. What I want to achieve is to rewrite ^ghana-radio-stations\/([^/]*)$ internally to

ghana-radio-stations.php?region=$1 [L]

this is the rule in my .htaccess file:

RewriteEngine On
RewriteRule ^ghana-radio-stations\/([^/]*)$ ghana-radio-stations.php?region=$1 [L]

I want this url ghana-radio-stations/ashantito map to ghana-radio-stations.php?region=ashanti

But this gives page not found error.
