var newwindow, when needed in a frame

The following code is from an old file I found and am trying to use. It's for a multiple drop-down box menu. It works, mind you, but the variable only allows me to either open in a new window or in the same frame. I'm trying to get it to open up in the "main" frame. For instance, in the first drop down box, I click goto for Home, and am taken to the body.htm file, but it opens in the same frame instead of the main frame. I've tried doing a base target tag in the header, but no luck. Any ideas?

Code: 
var onclickaction="goto" 

var newwindow=1 //Open links in new window or not? 1=yes, 0=no.


addListGroup("chainedmenu", "First-Select");

addOption("First-Select", "Select an item", "", 1); //HEADER OPTION
addOption("First-Select", "Home", "body.htm", "Home");
addList("First-Select", "Algebra 1", "", "Alg");
addList("First-Select", "Geometery", "", "Geom");
addList("First-Select", "Links", "", "Links");

If you insist

the first .js file:
Code: 
var onclickaction="alert"

function goListGroup(){
for (i=arguments.length-1;i>=0; i--){
if (arguments[i].selectedIndex!=-1){
var selectedOptionvalue=arguments[i].options[arguments[i].selectedIndex].value
if (selectedOptionvalue!=""){
if (onclickaction=="alert")
alert(selectedOptionvalue)
else if (newwindow==1)
window.open(selectedOptionvalue)
else
window.location=selectedOptionvalue
break
}
}
}
}

in goListGroup(), change
Code: 
else if (newwindow==1)
window.open(selectedOptionvalue)
else
window.location=selectedOptionvaluewindow.location=selectedOptionvalue
to
Code: 
else
parent.location=selectedOptionvalue

this should work

sorry, that changes the whole window. change it to
main.location=selectedOptionvalue

Im not sure if this is functionally differnet to
main.location=selectedOptionvalue;
but you could try
parent.main.location=selectedOptionvalue;
instead

If it aint broke, redesign it!
