Cannot read property 'left' of undefined

Question

Trying to figure out why chrome is throwing out error

"Uncaught TypeError: Cannot read property 'left' of undefined"

although #explorenav works great but #experiencenav doesn't seem to be working. am I missing something?

JS CODE:

$('.nav li#explorenav a').click(function(){
    $('body').animate({scrollLeft: $("#explore").offset().left-15}, 1000, function(){
        $(this).parent().addClass('active');
    });

    return false;
});

$('.nav li#experiencenav a').click(function(){
    $('body').animate({scrollLeft: $("#experience").offset().left-15}, 1200, function(){
        $(this).parent().addClass('active');
    });

    return false;
});

HTML CODE:

<div id="explore">
    <div class="Features">
        <div class="Feature1" title="The Active Park Assist feature can find parking spaces for you and help manoeuvre your car into them, as if by magic.">

            </ul>
        </div>
    </div>

Answer 1

In your script on site you have this code:

$('.nav li#experiencenav a').click(function(){
     $('body').animate({scrollLeft: $("#experience .EmptyPage").offset().left-20}, 1200, function(){
      $(this).parent().addClass('active');
      $('li#homenav, li#discovernav, li#explorenav, li#downloadnav').removeClass('active');
     });
      return false;
    });

and it can't find element $("#experience .EmptyPage"). But you have div inside your #explore div that has this div:

<div class="EmptyPage">
 &nbsp;
</div>

Thats why your code is working for explore link, but not for other links.
