framset question

[cbrooks]

I know, a lot of people say don't use frames/framesets use css, but you know how it is:

 

i have a site where 'index.php' sets up a page showing 4 frames for now just call them frame1..frame4

 

frame1 and frame4 never change, ever.

frame2 only needs to change 1 or maybe for extreme reasons 2 times.

all other activity happens in frame3.

 

Can I, while working in frame3 have frame2 update?

was told to try the following:

 

echo "<script language=javascript>frame2.window.location='partial_name.php';</script>";

 

but all is get is the following error: 'frame2' is undefined

 

 

any comments/sugestions/opinions/help will be appreciated.
