I want people to choose what site they want to search on. So i made a working search engine but how do i get the options to work? Here is a pic of my website
http://www.mediafire.com/view/?sv9zzdi94eqf0jz

as you can see there is 3 options, If you choose lets say ebay, if you choose the ebay option then when you search it would bring up ebay items. Get what i mean? now if you use the YouTube option then it would search for YouTube videos. So say you type in "how was google made" and then click the wiki option then i want wiki to come up and show the page "google".
My php

Search.php

$next $s $e;
$prev $s $e;
