I am trying to get some older Javascript from the
CoffeeCup DHTML Menu Editor to go again.

Years ago, I worked out that if I swapped
DcLoc.location.href=this.LinkTxt
//with
DcLoc.parent.frames[x].window.location.href=this.LinkTxt;
I could get things to work cross browser.
Nowadays, it seems that applying the Javascript is a little different.
My problem, to start, is this.
I find that when I apply my menu, I get a warning that
this line can't run anymore. Around 150 inside my web page.

var Doc=Par.document.documentElement;

Can someone reply with one line so that I can directly substitute
for this instruction to get things working again?
