There may be more efficient/better ways to do this, but this was the only way I could think of. Which is the use of player variables.

pawn Код:

new bool:helped[MAX_PLAYERS]; //Top of script

pawn Код:

CMD:fixveh(playerid, params[]) 
{ 

    new vehicleid;
    vehicleid = GetClosestVehiclePolice(playerid); 
    for (new checkvehicle; checkvehicle < MAX_PLAYERS; checkvehicle++) 
    if(IsPlayerInVehicle(checkvehicle, vehicleid)) 
    { 
        if(gTeam[playerid] == ASSISTANCE) // Learn how to use if statements 
        { 
            ShowPlayerDialog(checkvehicle, FIX_D, DIALOG_STYLE_MSGBOX, "Repair", "Would you like your vehicle repaired?", "Yes", "No"); 
            SendClientMessage(playerid, -1,"Repair request sent!"); 
            SetPVarInt(playerid, "Helped", checkvehicle); //Put the player-being-helped's id into a player variable.
            helped[playerid] = true; //Set the helper's helped variable to true (for use in the dialog response)
        }
        else 
        { 
            SendClientMessage(playerid, -1, "There isn't a player in this car"); 
        } 
    } 
    return 1; 
}

pawn Код:

case FIX_D: 
        { 
            if (!response) return SendClientMessage(playerid, 0xFF0000FF, "You cancelled."); 
            if(response) 
            { 
                RepairVehicle(GetPlayerVehicleID(playerid)); 
                SendClientMessage(playerid, -1, "Your Vehicle has been repaired."); 
                GivePlayerMoney(playerid, -500); 
                PlayerPlaySound(playerid, 1133, 0.0, 0.0, 0.0); 
                foreach(new i : Player)
                {
                    if(GetPVarInt(i, "Helped") == playerid && helped[i] == true) //This checks if the helper has helped playerid, and if his helped variable is set to true.
                    {
                        GivePlayerMoney(i, 500); // Give helper his money
                        helped[i] = false; // and set his helped variable to false (since he hasn't helped anyone)
                    }
                }
            } 
        }

Let me know if you have any trouble.
