added broken button buttons cart code continue copied correctly currency discount download drops empties five four html install lines load loads method multiple non-javascript normally opening option page particular pasted payment plus product shopping version view window

My discount shopping cart drops the first download, if i use the continue shopping option. It works with the other four quite well and goes through to the payment page. It loads to the cart but when you "Continue Shopping" and load another one it is not there. I can't see what I've done wrong as I used the same method to install all five buttons, plus the view cart button.

If that button is opening a new window, that means code for that particular button is not pasted correctly (like if it's broken in multiple lines) or you have added some other HTML to it OR it can also mean that you have copied the non-JavaScript version of the button.

However, if the button is opening the cart normally but just empties out the cart that means that you have set that particular product's currency different from the others.
