Routing issue with shopping cart
===

I am creating a shopping cart via Rails 3.0.10 & having an ongoing issues with it, so do hope someone here can help me getting it resolved please.

After getting NoMethodError in Carts#show  fixed-shopping cart working perfectly again, pushing & pulling via GitHub, Routing Error-No route matches is coming up! 


Does anyone know, what the problem is?


Thanks in advance for your help;-)
