*sigh* swf/php var/if

programming flash
1

login.php has an if statement that returns the following:

if ($pass == $memPW) {
    print "Status=welcome $memUN&***GO=1***";
} else {
    print "Status=username and password dont match&***GO=0***"; 
}

so far so good.
the flash has a button in frame one that requests the data and goes to frame two. i have a little indicator on frame two that even shows whether or not GO returns 1 or 0, it all works fine. the action script i have in frame two is shown below, and won’t automatically go to frame three, i have to click login twice… anybody know why??

stop();
if (GO == “1”) {
gotoAndStop(3);
} else {
gotoAndStop(1);
}
