Flash file won't work when live

hi, I seem to be having a problem with my flash file.

When I just play it locally on my computer in flash player it works fine, but when I put it on my server the buttons work once then do not work again.

Here is the code.

next_mc.onRelease = function(){
i = _currentframe + 1;
gotoAndPlay(_currentframe + 1);
container_mc.loadMovie(myLoadVars[“absoluteURL”] + “screen” + i +".swf");
countdown_mc.countdown = 6;
}

previous_mc.onRelease = function(){
j = _currentframe - 1;
if (_currentframe >= 2){
gotoAndPlay(_currentframe - 1);
container_mc.loadMovie(myLoadVars[“absoluteURL”] + “screen” + j +".swf");
countdown_mc.countdown = 6;
} else {
gotoAndPlay(6);
container_mc.loadMovie(myLoadVars[“absoluteURL”] + “screen6.swf”);
}
}

Any help would be greatly appreciated. Thanks in advance.
