I get the following error when I have more than 1 product in my cart (ie. 2 seperate products), and I try and delete a product from the cart :
A critical error has occurred.
'ddlCountry' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I have to go back to view cart each time, delete, get the error, until there is only 1 product in the cart - if I then delete that product the page reloads fine.
