Rotating Text Link

[Beauty]

I have a text rotating banner that I wish to add to my menu. The code to link to the rotating banner is:

<!-- banner start -->
<script language=javascript src=\"http://www.beautysarena.co.uk/thb/csBan ... "></script>
<!-- banner end -->

My Main Menu is:
//Main Menu
,\"Theme Arena\",\"show-menu=2\",,\"Theme Arena\",1
,\"Desktop Themes\",\"show-menu=3\",,\"Desktop Themes\",1
,\"E~Stationery\",\"show-menu=4\",,\"E~Stationery\",1
,\"Desktop Goodies\",\"show-menu=5\",,\"Desktop Goodies\",1
,\"E~Cards\",\"show-menu=6\",,\"E~Cards\",1
,\"Links\",\"show-menu=7\",,\"Links\",1
,\"Information\",\"show-menu=8\",,\"Information\",1
,\"Arenas\",\"show-menu=9\",,\"Arenas\",1
])

I have tried a few options one is here:
//Main Menu
,\"Theme Arena\",\"show-menu=2\",,\"Theme Arena\",1
,\"Desktop Themes\",\"show-menu=3\",,\"Desktop Themes\",1
,\"E~Stationery\",\"show-menu=4\",,\"E~Stationery\",1
,\"Desktop Goodies\",\"show-menu=5\",,\"Desktop Goodies\",1
,\"E~Cards\",\"show-menu=6\",,\"E~Cards\",1
,\"Links\",\"show-menu=7\",,\"Links\",1
,\"Information\",\"show-menu=8\",,\"Information\",1
,\"Arenas\",\"show-menu=9\",,\"Arenas\",1
,\"Rotating Banner\",\"http://www.beautysarena.co.uk/thb/csBan ... \"Rotating Banner\",1
])

But this loads a page with document write and the link I wish to have in the rotating banner.

I hope you can understand what I am trying to say and I also hope you can help me.

Thanks in advance.
