You are calling "create_users.php" in your $.get() method instead you should be calling "checkAvailability.php"..

And try this for your client side form:

var macs = {
getMacAddress : function()
{
    document.macaddressapplet.setSep( "-" );
    return (document.macaddressapplet.getMacAddress());
}}jQuery(document).ready(function(){
    var mac = macs.getMacAddress(); 
    $.get('/checkAvailability.php?mac=' + mac, function() { alert('yeah done'); })
});
