problem with your example.

Limit is not used that way

Check out this page for further explanation

http://dev.mysql.com/doc/refman/5.0/en/select.html#id3064319


Here is something I whipped together for this as an example


<?php

$page = 1;
$rowsPerPage = 10;
$start = 0;

if (
	isset($_GET['page']) &&
	is_numeric($_GET['page']) &&
	$_GET['page'] >= $page
	) {
	$start = ($rowsPerPage * floor($_GET['page']) );
}

$SQL = "select * from table LIMIT {$start}, {$rowsPerPage}"

display results...

?>

Let me know if I completely confused you.  I am often confusing...
