AJAX/PHP search suggestion problem

Okay so, Im working on a FAQ Page, but id like to make it so as the user is typing in information ajax will realtime display suggestions based on what strings are in the array.

So this is what i Have so far, but when i run the script. nothing happens at all and I cant seem to figure out what i am missing.

So here is my code:

Main Page with Search box (index.html)

<style>
body{width:610px;}
.frmSearch {border: 1px solid #a8d4b1;background-color: #c6f7d0;margin: 2px...

Code (markup):
