Load 2 Frames (possibly OT)

I need to load 2 frames from within PHP, I just don't know how to do it. I have tried header calls, I've tried echoing out the javascript command, but I need a way to load the pages at one time. Layout: add List see You use list to add information, when things are added in add they call another script to process the add. At the end of the add is when I need see to be loaded. I am pretty sure it is going to have to be a javascript, but even that I haven't found the code for yet. Any thoughts? My current code is: header("<script language=\"javascript\">parent.C.location.href = \"show.html\";</script>"); header("<script language=\"javascript\">parent.B.location.href = \"custn.html\";</script>"); Thanks, Robert
