Because you did:

pawn Код:

new cdveh = GetPlayerVehicleID(MAX_PLAYERS);

when it should be "playerid" instead of "MAX_PLAYERS" and cdveh is 0 and then using:

pawn Код:

GetVehicleName(cdveh)

will cause the run time error because you basically do: 0-400 which results to a negative index. You must check if the modelid is not 0 and subtract.
