echo string in a frame

[tripwater]

I have a index.html page that sets up my frames. THe first page that loads is a login page that first goes to a (access.php) page that does a query and checks their permissions based on their position. In other words I have flags set for supportrep,admin,developer and include the next page and show them the appropriate menus based on what they are allowed to see.

I am now converting the site over to frames and I have the index (login) page pulling up correctly but what I need to know is how do I now instead of including the page & it's relative menus, load my now separate menus and text pages into my frames built from index.html?

I just need to know how to echo a string in php into another frame.

I was told that this might have to be done using javascript.

THanks for any help.
