What is going wrong. Give us some more information. And jezus, you are using more enters then your whole script. Try something like this:

pawn Код:

CMD:duel(playerid, params[])
{
    if ( sscanf( params, "ud", params[ 0 ], params[ 1 ] ) ) return SendUsage(playerid, "/duel [playerid] [weapon id]");

    new tString[256];

    if (!IsPlayerConnected( params[ 0 ] )) return SendError(playerid, "Player is not connected.");
    if( g_HasInvitedToDuel[ params[ 0 ] ] == 1) return SendError(playerid, "That player is already invited to a duel!");
    if(IsNotWeapon( params[ 1 ] ) ) return SendError( playerid, "Not allowed weapon ID");

    //if(   params[ 0 ]  == playerid) return SendError(playerid, "You can not duel yourself!");

    if(!IsValidWeapon( params[ 1 ] ) ) return SendError( playerid, "Invalid weapon ID");

    new WeapName[32];
    new DWP = params[1];
