Fix Javascript Form Code

I have a simple web form that has some java script in it for form validation and to show a message to the user that the form was submitted. The original developer is not available and there is something wrong with the code. This should be a 2-3 min fix for someone that knows Javascript. Upon being chosen, You will be given a URL of the form and you can view the source code of the .html file and direct me on how to fix it. Part of the code that isn't working: submitHandler: function(form) { // [login to view URL]('submiting'); //[login to view URL](); $.post( $("#register-form").attr('action'), $( "#register-form" ).serialize() ).done(function(data) { [login to view URL](data); if(data == 1) { var success_msg = $("<div class='success-msg'>Thank you for your submission! We'll be in touch very soon!</div>"); [login to view URL]('.submit-wrapper').hide().slideDown(); } }); }
