I have not tested this, but I think this is a generic form or what you
want...
the main thing i see that can be wrong in your code is here:
len = parseFloat(obj.clen.value)
is this the length?? obj.clen.value?? maybe obj.clen.length
hope this helps....
////////////////////////////////////////////////////////////////
len=document.checkboxes.length
cnt = 0
for(i=1; i<=len; i++) {
if (document.checkboxes[i].checked == 1)
{
cnt++;
}
}
//cnt should be equal to the number that are checked....
