url of target frame

[elf]

how can i get the url of a target frame to pass to a form. i have a tool bar in the top frame and the user navigates the bottom frame. i need to have a way to get the url of the bottom frame so i can store it in a database as a bookmark.

thanks in advance,

elf

possibly can i use some form of:

document.getElementById('frame').src

to pass the info over?

Thanks again.
