Cannot read property 'settings' of undefined when I click submit button

If you use the rules() method, make sure to initialize the validation first.

var validator = $("#Form1").validate();
$('#field1').rules("add", {
         min: 1
});

You defined two ids with same name, whereas id should be unique.

<div class="col-xs-6" id="signUpForm">
<form role="form" id="signUpForm">

Try to remove id from <div class="col-xs-6" id="signUpForm">
