<script type="text/javascript" language="JavaScript">
function CountChecks(which) {
var maxchecked = 3;
var count = 0;
if(document.F1.R.checked == true) { count++; }
if(document.F1.G.checked == true) { count++; }
if(document.F1.B.checked == true) { count++; }
if(document.F1.Y.checked == true) { count++; }
if(document.F1.P.checked == true) { count++; }
if(document.F1.O.checked == true) { count++; }
if(count > maxchecked) {
eval('document.F1.' + which + '.checked = false');
}
}
</script>
</head>
<body>
<form name="F1">
