Simple Javascript not working on production

I have a javascript alert that works on PHPRunner's built in web server, but not when I move it to my production server:
In Javascript OnLoad event:

var ctrl = Runner.getControl(pageid, 'msg_date');

ctrl.makeReadonly();
this.on('beforeSave', function(formObj, fieldControlsArr, pageObj){

alert("Thanks for contacting us");

return true;

});

Live version not working at this site:

Contact Us Form
Thanks for any help

Thanks for the heads up John, where did you find that information??
The Google recaptcha is loaded by PHPRunner, not in my code. The domain is registered with Google:
