Why does my test POS transaction fail to load checkout?

[lolamays]

I am trying to run my first test pos transaction.  After selecting a customer and products, I click the "checkout" button.  I am then redirected to a screen that starts to say "Loading Checkout", but before it completes it redirects to a screen that says "Couldn't load checkout. There was an issue with the cart",  and my only option is the "leave checkout" button.  I cant find any help to guide me regarding what is set up wrong, or could be the problem.  I am in my test period and don't want to waste time on this issue.  Can you please provide me with the correction/s?  Thank you, Rebecca
