OK I tried searching for this but ummmm for some reason im not a good “searcher” for information because i don’t really know what i am looking for 😛  
Anyways though here is what i need.

When the url is index.php there is a dropdown box:  
\<select name=‘category’\>  
\<option value=‘1’\>Category 1\</option\>  
\<option value=‘2’\>Category 2\</option\>  
\</select\>

What i need is when the user click on one of the categories it changes the url to index.php?cat\_id={chosen category id}

I am using php and html (I don’t use flash :O). I know this is done with javascript but i am ignorant in that area as well. Anyhelp would be much appreciated 😃
