Did you just copy-paste them?

Declare PlayerInfo:

pawn Код:

enum _pInfo
{
    // ... (more)
    pTicket
};

new PlayerInfo[MAX_PLAYERS][_pInfo];

Remove the stock of GetDistanceBetweenPoints from line 3257 (and the rest of its code) because it already exists.

Remove:

pawn Код:

#define COLOR_GREEN 0x05FF00FF  
#define COLOR_RED 0xFF1E00FF

Add it to the bottom:

pawn Код:

IsPlayerInArea(playerid, Float:MinX, Float:MinY, Float:MaxX, Float:MaxY)
{
    new Float:X, Float:Y, Float:Z;

    GetPlayerPos(playerid, X, Y, Z);
    if(X >= MinX && X <= MaxX && Y >= MinY && Y <= MaxY) {
        return 1;
    }
    return 0;
}

For IsModelAPlane and IsModelAHeli, ****** them.
