Mi lehet a hiba ebben a scriptben? Miért nem működik?

<div id="SUB" ;=""

style="display: none; overflow: hidden; width: 1px; height: 1px; left: 0px; top: 0px; position: absolute;">=""

align="center"><font

style="font-family: Impact; text-decoration: none; font-weight: bold; font-style: normal; color: rgb(105, 221, 221); font-size: 64pt;">szöveg

</font>

<script>

<szöveg>

var StartDelay = 1*1000;

var RepeatDelay = 1*500;

var RepeatTime = 1000;

var Opacity = 100;

window.onload=Sub; Sub(); function Sub() { document.getElementById('SUB').style.width = document.body.clientWidth; document.getElementById('SUB').style.height = document.body.clientHeight; setTimeout('SubOpenIt()',StartDelay); } function SubOpenIt() { document.getElementById('SUB').style.opacity = (Opacity / 100); document.getElementById('SUB').style.MozOpacity = (Opacity / 100); document.getElementById('SUB').style.filter = "alpha(opacity=" + Opacity + ")"; document.getElementById('SUB').style.display='inline'; setTimeout('SubCloseIt()',30); } var x = 0; function SubCloseIt() { document.getElementById('SUB').style.display='none'; x++; if (x < RepeatTime+1) setTimeout('SubOpenIt()',RepeatDelay); }

</script>
