Minor mistake:

pawn Код:

new count[2];

Your variable was out of bounds.

And it can be done simply just:

pawn Код:

new count = 0,string[32];

public OnPlayerEnterCheckpoint(playerid)
{
    new n[MAX_PLAYER_NAME]; GetPlayerName(playerid,n,sizeof(n));
    count++;
    format(string,sizeof(string),"\"%s\" has entered the %d checkpoint, %d left.",n,count,4-count);
    SendClientMessageToAll(color,string);
    return 1;
}
