htaccess mod_rewrite help

hi,
i need some help with .htaccess

i want urls like:
www.bla.com/gallery.php?what=disco&place=kiss&date=12112007&pic=3

to be shown like:
www.bla.com/gallery/disco/kiss/12112007/3/

i use
RewriteRule ^gallery/(.*)/ gallery.php?what=$1
RewriteRule ^gallery/(.*)/(.*)/ gallery.php?what=$1&place=$2
...

but this only works when your url is www.bla.com/gallery/disco/
when your url is www.bla.com/gallery/disco/kiss/ (...) doesn't work.

so, can someone help me somehow?
thanks!

 

Try changing
RewriteRule ^gallery/(.*)/(.*)/ gallery.php?what=$1&place=$2
to
RewriteRule ^gallery/(.+?)/(.+?)/ gallery.php?what=$1&place=$2

 

That shows me Internal Server Error.

 

This this one:

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/([^/]*)\.html$ /gallery.php?what=$1&place=$2&date=$3&pic=$4 [L]

It doesn't have the word gallery in the URL, but it's a start.

 

Shows me Error 404.
