I have a html file:

<body>
  <?php 
    $rand1 = rand(0,10);
    $rand2 = rand(0,20);
  ?>

  <span id="client-registration-button">Registration</span>

  <script>var checksum = <?php echo $rand1+$rand2; ?>;</script>
  <script src="/main.js"></script>
</body>

And in main.js is:

$('#client-registration-button').click(function() {         
    alert(checksum);    
});

But the alert shows no value, just empty alert window. Why is there no value of global variable "checksum" displayed?
