 Q:

Display alert message if checkbox isn't checked

I am trying to show a message if the checkmark on this page is not checked - https://www.hawaiidiscount.com/rental-cars/oahu/honolulu-airport.htm
See where it says "I'm aware Alamo has additional fees, paid directly to Alamo at the counter when picking up the vehicle."
On a static page the script below works correctly (for example if you download the page and place the code in the body). But when the page is live, it is not working.
<script>
$('#dnn_ctr367_CartQuickView_anchBookNow').click(function () {
    if (!$('.cartcheckbox').is(':checked')) {
        alert('Please check the box - I\'m aware Alamo has additional fees, paid directly to Alamo at the counter when picking up the vehicle.');
        return false;
    }
});
</script>

Any idea what might be wrong?
EDIT:
When you click on the book now button there is text that appears on top of the cart (that's in case you didn't put any of the required information). So it seems this text is part of a program that ignores the script above. Is there a way to make my script to activate before the

 Since the vector $ b $ is arbitrary, it follows that the columns $ A_1,\ldots, A_{12 } $ of $ A $ are vectors that generate the quad $ \mathbb { R}^{10 } $.
