Why can't I add multiple items to my cart on GaryGraham422 using a laptop or cellphone?

Hi,

I noticed that when I try to add more than one item to my cart at 
GaryGraham422, when using a cell phone or laptop, I cannot checkout. This is only a problem with these devices.

Gary Graham 422 website allows multiple items added when using my desktop and leads the customer to checkout.

Can you help fix this bug? We want to ensure that our customers can add and checkout with multiple items regardless of the device they use to shop with.

Thank you in advance for your help with this matter.
