I think the reason I don't see the trigger choice for Clear Cart button pressed is because the of where I place the field and button for the discounts. I'm not sure but the only time I would see the clear cart trigger choice is when I put the discount fields in a div that was outside of the main cart div. That is the file I sent you last night.
The attached cart is with the coupon field inside the main cart div. I manually entered ""eCart1_Clear_100_x"" in the code for the ClearSession behavior. I got that button choice from the version where the discount fields were outside the main div. This appears to work fine, BUT now my main Checkout button is doing nothing when going to check out with something in the cart.
So I guess that is now my main question. Checkout button not working.
