                GivePlayerMoneyEx(killerid, Account[Account[playerid][DuelInviter]][Bet] * 2); 
                SendClientMessageToAll(pCOLOR_LIGHTBLUE, duelmsg); 
                CompleteDuel(playerid, killerid);

I think that you didnt declare duelmsg ?

Idk, try it and tell me if it's working or not.

Edit : I am talking about the msg that's being sent to everyone.
Edit #2 : If that's not what are you talking about, Then please describe the problem.
