Problem med FoldoutMenu2

Til dem der ikke kender den:
http://www.dhtmlcentral.com/script/script.asp?id=25

Jeg har lidt problemer med at få den til at virke. Den kommer med en fejl i linie 98:
nest=(!nest) ? "":'document.'+nest+'.';

Da jeg naturligvis ikke har rettet i den del af scriptet, må det nok ligge i denne del af koden:

<div id="divFoldCont">
    <!-- Top 1 -->

    Here's how it would look if we added one more top menu.

    </div>
    <!--
    Note all the places the numbers changed:
   
    divFoldCHANGED
    foldmenu(CHANGED)
    imgFoldCHANGED
    divFoldSubCHANGED_0
    subfoldmenu(CHANGED,0)
    imgFoldCHANGEDSub0
    divFoldSubCHANGED_0_0
   
    Locate those places to see where the numbers should be increased by one each time.
    If you add more topmenus be sure to change the "mainmenus" variable
    and add it in the "submenus" array.
-->   
</div>

eller her:

mainmenus=7 //How many main menus do you have?

//How many submenus do you have beneath each main level.
submenus=new Array(1,0,0,0,0,0,0)

dvs. kun en undermenu med kun et menupunkt.

Er der nogen der kan se fejlen?
