We have been getting "object reference not set to an instance of the object" error messages when trying to Update Quantity or Delete the Quantity (by hitting the X icon - and one time I got a message saying "there is no row at position 0").

The only pattern I have seen - it seemed to happen regularly when we not yet entered anything in the Ship To fields below the cart. Using chrome, ie 7, safari 5.03 and 5.04.

It was working last week and now, just tonight typing this up, I am not getting the error.  Can you shed any light on this?

Thank you!

This morning it is still a problem.

Right after adding to cart, changing the Qty 1 to 2 and hitting Update, returns the Object reference error.

Getting error with the following browsers:

Internet explorer 8.0.7601.17514

Firefox 3.6.17

Safari 5.0.3

Chrome - latest version

However, when I go to the store page (onlinestore.aspx) and add to cart from that page, the update function works fine. Is there something I need in the "add to cart" link that I set up on my other web pages?

I apologize but the site might be giving another error message right now based on other work someone's doing.

STILL GETTING THE ERROR - the "Object Reference" error when hitting Update Quantity but consistently AFTER adding an item to the cart from any of my product pages. I am NOT getting the error if I do this from the online store.

I looked at SmithCart instructions for creating that Add Item link and believe I am doing it right (by adding an item from the online store, viewing the cart, grabbing the URL - or just viewing the cart from the store and adding ?productid=1 to the end of the url).

I experimented with adding https (since the online store link is an https and I recently installed security certificates from authorize.net and Geotrust) and making sure the URL followed the store url (ie .../OnlineStore/tab... vs ...Products/ShoppingCart/tab...).

I hope someone has some insights. Thank you.

Still getting the error when updating quantity, just as described above: when adding to cart from a page in which I have put the "Add to Cart" link (as described by Smith Cart). But NOT getting the error when adding to cart from the online store.

I need this resolved very soon! 

Thank you for any assistance.

Hi Sean,

The update quantity issue is currently in programming and the expected release date is next week.

Thanks, Kevin

Hi Sean,

For some reason I was thinking that you were running 4.28. To confirm the issue is fixed in the latest version of the cart you can download the trial version and then upgrade to the latest build to fix the issue.

Thanks, Kevin
