# How do I know how many users go to page C from page A through page B using Google Analytics? [duplicate]

Let's say I have a shop where the shopper have to login first, for the sake of example. There is a page called /cart where users can see all of the products they added to the cart from previous pages and proceed with the checkout. If the user is not logged in yet the /cart will go to /login and then will go to /success. Otherwise it will go to /success directly.

Using Google Analytics, how do I know

1. How many users want go to through the trouble of putting their credentials to process the cart?
2. How many users don't want to do it?
3. How many users that are already logged in, i.e. don't go through the /login? (assuming I don't track the user type using Custom Variables).
