eCart 6 adding multiple items with one add to cart button.

Hi,

I have set-up a event registration form where the user can select the number of show seller spaces, tables needed etc.

They can fill out the form using multiple text inputs and then click the add to cart button.

If they add one service at a time to the cart and then return to the page by clicking the "continue shopping" button from the shopping cart and add another service, the cart functions perfectly. But if they add multiple services to the cart at once, while they are displayed in the cart, if the user changes a quantity, all the quantities will change. If an item in the cart is deleted all the items in the cart disappear.

Any help is appreciated,

Thanks
