game error?

[islanderfan]

Been trying to get this as opening moves, but it keeps saying there's an error. Someone want to tell me why?
1.e4 e5 2.Ng1f3 d6 3.Bf1c4 Bf8e7 4.c3 Bc8d7 5.O-O Bd7c6 6.d4 exd4 7.Nf3xd4 Bc6xe4

You are probably using the letter O to indicate castling, but try using the number 0 as all moves should be indicated by a number. I tried to set up this opening using the number 0 and it worked.
