Error message on order

On this page, http://horizonaudiology.com/buy-accessories.php, placing some items in the cart generates an error while choosing others do not. If you choose any of the phones, the cart displays as expected. However, if you add most anything else (like the desktop alarm) to the cart, this error appears at the top of the next screen:

Warning: Missing argument 10 for horizon_Definition::AddToCart(), called in /home/content/25/11572325/html/buy-accessories.php on line 189 and defined in /home/content/25/11572325/html/WA_eCart/horizon_PHP.php on line 28

Warning: Cannot modify header information - headers already sent by (output started at /home/content/25/11572325/html/WA_eCart/horizon_PHP.php:28) in /home/content/25/11572325/html/buy-accessories.php on line 381

This error normally happens when you edit the cart object to add columns.

If you add columns i the cart object, you need to edit the add to cart behavior to have the code re generated for the new section of columns.

So just open the Add to Cart object and close it? Do I do that for each item?

Yes, on the server behaviors panel, open each instance of the add to cart server behavior. If no changes need to be made, click OK, otherwise if the new column that was added needs a binding, make that change on the bindings tab.

Got it, thanks!

You're welcome.
