<!-- TWO STEPS TO INSTALL LIMIT BOXES:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  -->

<!-- STEP ONE: Paste this code into the HEAD of your HTML document  -->

<HEAD>

<SCRIPT LANGUAGE=\"JavaScript\">

<!-- Begin
function countChoices(obj) {
max = 3; // max. number allowed at a time

box1 = obj.form.box1.checked;  // your checkboxes here
box2 = obj.form.box2.checked;
box3 = obj.form.box3.checked;  // add more if necessary

count = (box1 ? 1 : 0) + (box2 ? 1 : 0) + (box3 ? 1 : 0);
// If you have more checkboxes on your form
// add more  (box_ ? 1 : 0)  \'s separated by \'+\'

if (count > max) {
alert(\"Oops!  You can only choose up to \" + max + \" choices! \\nUncheck an option if you want to pick another.\");
obj.checked = false;
  }
}
//  End -->
</script>
</HEAD>

<!-- STEP TWO: Copy this code into the BODY of your HTML document  -->
