I'm trying to create a "scrolling pagination" (similar to Facebook) except users have to click to load more content.

This is my javascript function. I'm using Jquery.
//Start Code
function GetMore(){
url: 'phpfile_that_echos_content.php',
success: function(data){
//End Code
The php file gets queries from the database and formats the information based on what type of content it is. The php file works without the ajax call.

I call it using a clickable image...
<a href="javascript: GetMore()">
<img src="image.png" />
However, when I click the image, it does not show. When I append data to the content div without using $.ajax, it works. My site is hosted on Godaddy with a Linux server and I'm using PHP. Does anyone know why my code isn't working?
