PHP and Flash variable problem

How come this doesnt work:

myVars = new LoadVars();
myVars.load(“testfile.php”);
trace (variName);

the PHP file has
<?
echo “variName=HelloWorld”;
?>

Any help would be great.

excactly. forgot about the onLoad…
stupid of me! :-/

You guys are boarder line geniuses…lol. Thank you. One other quick question. The myVars.variName variable does not exist outside the myVars.onLoad brackets…is there a way to use it outside the brackets?? I guess I am still a noobie.
