javascript: open a new window in my frame, HELP!?

have been doing html, css, javascript squarely over 2 years... and am now doing a family project.. in my project i have decided to use a context menu script, its a menu that pretty much allows for when you right click on a page it shows you different links that the standard right click menu, link here:
http://www.dynamicdrive.com/dynamici...ontextmenu.htm
What it does exactly is opens a new window with the link that you have chosen, on the link that i have given above the demo is in the page, right click anywehre, and you'll see... now.. like is said it opens with a right click,... the problem that i am having is that when a window opens...it opens in a new window... i want it to open in one of my frames, here is the code snippetplease notice that this is all internal javascript, therefore it is in the body of the site)

<div id="ie5menu" class="skin0" onMouseover="highlightie5(event)" onMouseout="lowlightie5(event)" onClick="jumptoie5(event)" display:none>

i've figured out its this part thats responsible for the function of a new window... im using FRAMES, not IFRAMES...


function jumptoie5(e){
var firingobj=ie5? event.srcElement : e.target
if (firingobj.className=="menuitems"||ns6&&firingobj.parentNode.className=="menuitems"){
if (ns6&&firingobj.parentNode.className=="menuitems") firingobj=firingobj.parentNode
if (firingobj.getAttribute("target"))
window.open(firingobj.getAttribute("url"),firingobj.getAttribute("target"))
else
window.location=firingobj.getAttribute("url")
}
}

i've changed the last line (window.location=firingobj.getAttribute("url")
to the following:

document.getElementById("kirupa").src=firingobj.getAttribute("url");
kirupa.location=firingobj.getAttribute("url")
Kirupa.document.location=firingobj.getAttribute("url")
document.frames[kirupa].location=firingobj.getAttribute("url")
document.frames["kirupa"].location=firingobj.getAttribute("url")

...nothing works.. help?
