Thanks for your quick response.
I was working on the tags_double_rbtest.php into which I had added many new fields. After that error happened I restored back to the old cart object and cart_static. So now I have uploaded all the other pages with cart buttons but the tags_double_rbtest.php page came up with a message (screenshot attached) when i opened it and would not let me do the procedure with the cart button. That is where i am right now...
That tags_double_rbtest.php page is screwed up but at least it is a test page so I will probably want help figuring that out on Monday. I know the cart object & cart_atatic are no longer correct (since I restored old one). But I'm sure there are other messes in there as well!
