Wrong product going to checkout page

[buylocalmv]

I have 8 items in my store (all with unique names). Everything works fine until you click add to cart. On the checkout page it displays my first product no matter which product you’ve selected. This is a huge problem and I can’t find any information on how to fix this. I wish there was a troubleshooting page for help or a phone number to call when you need help. Instead it takes hours of searching for someone who’s had the same issue and I’m not finding anything related to this issue in the forum search. Can anyone help me here? The site is buylocalmv.com Thank you!
