It looks like it is part of a switch statement, but not under a specific case, are you sure the rest of the syntax is correct? Also it should not be <= MAX_PLAYERS, unless you're using a custom MAX_PLAYERS value. As MAX_PLAYERS is 500 and ID 500 is never used in SA-MP, that is why we always do < MAX_PLAYERS.

Also as the error says, you can only have one statement or expression in a case, so you'll need to work around that also.
