Javascript (How to display results two inline frames)

Hi,

I have a website I'm trying to create if you look at www.onlinejobs.com.au/xintro.htm for details.
On the xintro.htm file there is two inline frames
Frame 1) On the Left is a search Option
Frame 2) On the right Where the pictures are if you select
         the chatroom you will see the frame change.

On the left is a search option (Frame 1) when searching when you click submit it returns the results in a seperate page (pop up).
I want the results to be inserted into the frame on the right (Frame 2.

To get the search results to open up on a seperate webpage I added the below(Target).
How do I tell it to display the results in the frame 2. (HOPE THAT MAKES SENSE)

Search Page (Html Source)
<form action="seeker_jobresults.asp?NDX=0&ORD=10" method="post" name="form1" onSubmit="return enviar()" onKeyPress="checkkey()"target="main.htm">
