Program.cs(33,16): error CS0136
This comes up, and does not change even when I change the string 'entry' to something like 'item'.

It looks like the code in the loop somehow got duplicated again after the loop. Get rid of the duplicated code and that should fix the issue.
But you'll also need some additional code inside the loop to change the value of "keepGoing" so the program can end when the user wants to quit.
