How do clear the iframe in netscape 7.0 and Internet explorer. The following code works in IE but not in netscape
<html>
<head>
<title>Simple Math Practice</title>
<script language="javascript" type="text/javascript">
<!-- Hide Script
function RandPosInt() {
Rnum = Math.round(Math.random()*8+1);
return Rnum;
}
function WriteHeader() {
problem.document.write('<html><head><link href="math.css" rel="stylesheet" type="text/css"><\/head><body>');
}
function WriteContent() {
problem.document.write("this is content");
}
function WriteFooter() {
problem.document.write("<\/body><\/html>");
}
function ClearFrame() {
problem.document.open();
problem.document.clear();
}
function CloseFrame() {
problem.document.close();
}
// End Hiding Script -->
</script>
