DeclarationError: Identifier not found or not unique for msg.sender

[ParkerZA]

My code is pretty much the same as Patrick's at this point in the video (timestamp). Except his code compiles and mine throws the error: "DeclarationError: Identifier not found or not unique" pointing to "event RaffleEnter(msg.sender);" with ^^^^ under msg.sender.
