Javascript Problem

djcochran · May 3, 2009

I recently converted all my html pages into php pages, and in doing so, well...I can't seem to figure out how to get the javascript function checkout() to work at all! It used too...now it doesn't. I know this may be a lot to go through, but if anyone would mind looking through and maybe seeing what could be the problem? Thanks!

<?php
session_start();
$file = fopen("template2.data", "r");
while(!feof($file)) {
$line = fgets($file);
if(preg_match("/@@CONTENT_HERE@@/", $line, $dummyarray)){

print<<<END

You know there's a JavaScript forum, right?

Are you saying the function doesn't run or it's getting wrong values?

I guess it won't run at all. Like...when I click the 'Checkout' button...the alert message doesn't appear.
