Normal iFrame Break out doesnt work - Help please

[PepsiHack]

Ok i am developing a site on a server that only allows HTML and some Java Script - The Server displays my pages in its own layout. I tried to set up hosting somewhere else, however the organization has to host on this server.At first i couldnt even use CSS to style the page. However up to this point I have used javascript to impliment CSS and an external server to host scripts and images and css on. Heres the problem:
there is a chat room through the server. I used an Iframe to put it into my layout - which is in their in their layout. It links back to the home page but when clicked it reloads the home page in the i-frame. I cant edit the

<a href="#" target="_top">

so i figured i would put javascript on the Home page that could detect that it was in the iframe and reload itself in the same window but without the iframe:

the home page is at http://www.lutheransonline.com/yolocountychapter then click on chat rooms:

now in this window the chat room is in an iframe and right above it sits two links
[Home Page] [Chat Room] clicking on Home Page opens the home page in the iframe - I have tried alot of ways to break this.

Once again i can not edit the links - the chat page in the iframe is dynamicly generated. Any Help would be great.

In addition I cant even get it to recognize that its loaded in the iframe - i am trying to get it to just recognize its in there and throw an alert but to no avail

UPDATE:
ok im using:

parent.document.URL = "http://www.lutheransonline.com/yolocountychapter/home"; 

to break away from the ifram however i need some kind of statement or some other way to tellit to stop otherwise it gets stuck in a loop.

i've tried a bunch of if statements to no avail

UPDATE:
Figured It Out Thanks i used

if (parent.document.getElementById("chatframe"))
parent.document.URL = "http://www.lutheransonline.com/yolocountychapter/home";

probably a no brainer for most - just getting started with this stuff
most of my problems i think were syntax
