js 在火狐和ie的兼容性问题

我都把marquees 改为 document.getElementById("marquees") templayer改为 document.getElementById("templayer")为什么还是在ie能浏览在火狐上就不行了呢
<table width="214" border="0" cellpadding="0" cellspacing="0" background="img/lefttitle1.jpg" >

          <td height="30" class="lefttd"><div style="margin-left:40px;">都市114</div></td>
