Tutorial on displaying MySQL in flash doesnt work!

I followed the tutorial word for word and even the first basic part didnt work. I got “_level0.instance1.myVar” in my dynamic text box instead of my variable. The text box’s variable name is myVar. The AS I wrote is as follows
[AS]onClipEvent (load) {
loadVariables("/mysite/php.php", this, “GET”);
}
[/AS]
and the php is

<?php
$x = "abc";
print x;
print "myVar=$x"
?>

.
When I acess the PHP page, it displays the info correctly but the SWF gives the error mentioned above. I would really appreciate some help.
