Play() works in FF not in IE

Question

Hello i'm trying to play just the first few seconds on a quicktime movie then stop. if the user scrolls, I replay. By design, once the user clicks 'Play' I want the movie to disregard the scroll (and other) functions. This seems to work in FF, but not in IE, where the movie will not even play initially. I'm getting a 'document.movie1 undefined error'. Any help is much appreciated. Here is the code....
<script src="include/javascript/AC_QuickTime.js" language="javascript" type="text/javascript">
</script>
<script type="text/javascript" src="include/javascript/mootools-1.2.5-core-nc.js"></script>
<script type="text/javascript" src="include/javascript/Quickie.js"></script>

Make sure that you do not use bgsound to pay that music.
