frames divs variables javascript.

I have an application that uses frames; in one of the frames I have a variable that gets changed dynamically by php code and a java applet. This variable changes often during any single browser session.

I need to accomplish the following:

In frame A I need to display variable "artistid" that I retrieved from frame B without reloading frame A:

I know how to get the variable like this:

var artistid = top.frames[3].pick3.artistid;

I need this to happen every few seconds automatically, without any clicking or rollovers or anything.

It has to work in IE4+ and NS4+

I know it has to do with layers and divs, and I know I will need some kind of setTimeout call but I am vary new at JavaScript and I can't figure this one out. PHP and Unix shell I'm good at but not JavaScript.

I know how to get it done using JavaScript and php IF I reload the frame but I have a lot of stuff in that frame and I don't want to reload it again, I just want to display the value of "artistid" every few seconds after having again retrieved it from frame A in case it has changed.

Can you please help me or point me to someplace where I could find what need?

Thank you so very much for your help

Could give this a shot...

.artist {

<script type="text/javascript" language="JavaScript">

var IDtimer = null;

function setCell() {
var cell, artistid = 'Bob Dylan'; // top.frames[3].pick3.artistid;
if (artistid) {
if (!document.layers) {

if (cell && typeof cell.innerHTML != 'undefined') cell.innerHTML = artistid;
} else {

cell.document.write('<span class="artist">' + artistid + '</span>')
cell.document.close();

}
}

onload = function() {

onunload = function() {
