You used GetName(playerid) function in your code and you gave him GetNameEx(playerid) which will output another error.

pawn Код:

GetName(playerid) {

    new sz_playerName[MAX_PLAYER_NAME];
    GetPlayerName(playerid, sz_playerName, MAX_PLAYER_NAME);
    return sz_playerName;
}

This code should be posted anywhere in your script outside of any function or callback. (e.g. After all '}' of a function are closed)
