Where does the loop() function end in your program ?

I see the declaration for "void dislay(char dig)" right after loop(), but I don't see a function named "display()". The compiler will do what you say to do, not what you mean to do.

Time to start using an editor with a good auto-complete, then spelling errors like this are much harder to make.

Rubbish. Visual Studio does auto-complete, and f*cks up more than it "helps".
