[development] Form API and Javascript stuck

[Karyn Cassio]

In case anyone is still awake:

Drupal.behaviors.compute_items = function() {
     $(".line-item-quantity").bind("change",function() {
       // The id of this should be edit-quantity-ID so we use replace
       var id = $(this).attr('id').replace('edit-quantity-', '');
     //  alert('edit-quantity-' + id);
       var quantity = $('edit-quantity-' + id, this).val();
       alert(quantity);
       var price = $('edit-price-' + id).val();
       alert(price);
       var subTotal = quantity * price; // Do your actual calculation here.
         alert(subTotal);
       subTotal = isNaN(subTotal) ? 0 : subTotal;
         alert(subTotal);
       $('edit-subtotal-' + id).val(subTotal);
       alert('edit-subtotal-' + id);
     });
};

quantity and price are returning *undefined*.

Thoughts?
