i dont know how to get .htaccess to work in my page?

OK, so lets see i have a working link

http://hellow/app/view/apps.php?c=BANK&nom=LOLx3&n=1016

And i have this htaccess script for my link:

RewriteEngine on
RewriteCond %{QUERY_STRING} c=([^\&])
RewriteCond %{QUERY_STRING} nom=([^\&])
RewriteCond %{QUERY_STRING} n=([^\&]*) RewriteRule apps.php$ %1/%2/%3? [NC]

I tested here so it works perfectly.

My doubt comes when i put this script in my .htacces ,who is in the same folder as my index.php. I will explain what i´m doing so tell me what is wrong.

• 1.I paste the script above in my .htaccess file.
• 2.I am trying to access with this link==> http://hellow/app/view/apps.php?c=BANK&nom=LOLx3&n=1016
• 3.The server gives me a 404 Error i think this is fine

• 4.Then i am trying to access with this link==>http://hellow/app/view/Bank/LOLx3/1016

• 5.And my server gives me a 404 Error

• 6.If a comment all that script in my .htacces everything is working like before.

What i am doing wrong?
