<script>
function myFunction() {
  // Get the checkbox
  var checkBox = document.getElementById("chkNIRF");
  // Get the output text
  var Check-content = document.getElementById("text");

  // If the checkbox is checked, display the output text
  if (checkBox.checked == true){
    text.style.display = "block";
  } else {
    text.style.display = "none";
  }
}
</script>
<script>
function myFunction() {
  // Get the checkbox
  var checkBox = document.getElementById("chkNAAC");
