The relevant part of the code is shown below. When I click the Submit button, on the alert box, I get undefined, rather than the typed email. What mistake am I doing here?

<form action=page2.php method=post onsubmit=myFunction() id=form1> 

        ......

        <input type=text name=YourEMail style=width: 250px;> 

        <input type=submit name=submit value=Submit> <br>

        ......

</form> 



<script>

$('#form1').submit(function() {

    //your validation rules here

    var email = $('#YourEMail').val()

    alert(email)

    //if(email.length == 0)

        return false;

    //else 

    //  return true;

});

</script>
