Exchanging data between page and popups?

[bjblackmore]

Hi,
I have my own web based email, and I want to add an address book feature. I'd like to have a link, on my compose email page, so you click on it, and a popup window opens with all the addresses, easy enough. However I'd then like to click an address, and have it auto fill the 'To' field on the original compose email page. This could be done with checkboxes, so you tick the address, and press 'submit' and the popup would close, and the 'To' field would be auto filled.
I think I've seen it done else where, does anyome know how to do it? Or is it more a java type thing?

IMO this is a javascript problem, not php

Yeah thought so. Just found a very nice script, does exactly what I want.
http://javascript.internet.com/forms/items-popup-list.html
just need to convert it to php now, so it pulls the items on the list off the database.
Cheers
