Hmm never made it like you did, just try it like this:

pawn Код:

YCMD:buynitro(playerid, params[])
{
    if(IsPlayerDriver(playerid))
    {
        if(IsPlayerInRangeOfPoint(playerid, 7.0, -216.4033,1048.0056,19.7422))
        {
            if(PlayerInfo[playerid][VehNitro] == 0)
            {
                PlayerInfo[playerid][VehNitro] = 1;
        return 1;
            }
        else return SCM(playerid, COLOR_GREY, "You already have Nitrous in your vehicle.");
        }
    else return SCM(playerid, COLOR_GREY, "You're not at Nitrous Shop");    
    }
    else return SCM(playerid, COLOR_GREY, "You're not in a vehicle");       
}
