javascript rollover in navigator

[cill]

I am using Golive on a Mac platform to create a navigation component for a website I am designing. I picked up the following piece of javascript to change the background color of a cell on a mouseover. Everything works great in Explorer on mac and pc, but navigator is not recognizing it on both platforms.

Is there anything I can do to alleviate this problem?

<td id=&quot;navCell&quot; bgcolor=&quot;#663399&quot; onMouseOver=&quot;this.style.background='#330066';&quot; onMouseOut=&quot;this.style.background='#663399';&quot;>option</td>
