form.submit with JQuery

I have the code below to advance through a multi-part form for signup. Need it to not submit until we reach the end, and am having issues with the form not submitting.

Any help would be appreciated?

Regards,

My code is;

    $(function(){
//original field values
var field_values = {
        //id        :  value
        'username'  : 'username',
        'password'  : 'password',
        'cpassword' : 'password',
        'firstname'  : 'first name',
        'lastname'  : 'last name',
        'email'  : 'email address',
        'address1' : 'address 1',
        'address2' : 'address 2',
        'city'      : 'city',
        'zip'       : 'zip',
        'refer'     : 'referrer '

};


//inputfocus
$('input#username').inputfocus({ value: field_values['username'] });
$('input#password').inputfocus({ value: field_values['password'] });
$('input#cpassword').inputfocus({ value: field_values['cpassword'] }); 
$('input#lastname').inputfocus({ value: field_values['lastname'] });
$('input#firstname').inputfocus({ value: field_values['firstname'] });
$('input#email').inputfocus({ value: field_values['email'] }); 
$('input#address1').inputfocus({ value: field_values['address1'] }); 
$('input#city').inputfocus({ value: field_values['city'] });
$('input#zip').inputfocus({ value: field_values['zip'] });

})

Change

$('#submit_fourth').click(function(){
    //send information to server
    $('form').unbind('submit').submit(); 
});

You need that because at the beginning you have $('form').submit(function(){ return false; }); which will make all attempts to submit to fail..

Your code should be like this.

$('#submit_fourth').click(function(){
    //send information to server
    alert('Data successfully sent');
document.form.submit();
});
