Still empties cart
Unfortunately that does not help with the single "add to cart" buttons - whom have no "option" associated with them, I have the ID number, Name, Description all set to unique now and have updated the ecart object etc live - it still empties the entire shopping cart if two or more are selected
In relation to the drop down menu - I have both the Label and the Value populated - again if you click the first and the third to tell it to remove and click update cart it empties the whole cart. I do not have an "Options" field - I am not sure why I need one of these if I am simply (as per your first reply) putting the options under the Description (unique) on the button - or do you want me to try to create this button another way now?
So both types - whilst they can go through to the cart it empties when you click to remove one and three or two / four etc - you can see what it is doing through the page supplied.
