assuming you have given the checkboxes the same name, the following code may help...


<form name=theForm>
<input type=checkbox name=myCheck>Check 1
<input type=checkbox name=myCheck>Check 2
<!-- etc -->
</form>
<script>
function CheckBoxes()
{
var i, n = document.theForm.myCheck.length;
var count = 0;
for ( i = 0; i < n; i++ ) if ( document.theForm.myCheck[i].checked ) count++;
if ( count > 5 ) alert('Too many checkboxes');
}
</script>
