sorry if this was discussed before. but i have to ask this question again.

I have a windows media player on my site. It's working fine with IE but not in firefox. I used javascript to play a video when the image is clicked. here is my code. if the settings for autostart is true, it works fine. i tried setting the autostart to true if the browser is firefox but its not working also. im getting an error document.getElementById("player").controls is undefined


function change(){
changepage('watch');
document.getElementById("player").controls.play();
}


<table border="0" cellspacing="0" cellpadding="0"><tr>
<td><a onClick="change()" onMouseOver="this.style.cursor='hand'"><img src="imgs-ppv/purchase1.jpg" width="83" height="22" border="0" /></a></td>
</tr></table>
