You get errors of target mismatch?

How do I fix this?

To do, If player is not in a vehicle, Sendclientmessage, You are not in a vehicle!!

pawn Код:

if(GetPlayerState(playerid) != PLAYER_STATE_DRIVER))
{
    SendClientMessage(playerid, -1, "ERROR: You are not in a vehicle!");
    return 1;
}

You don't need to keep those 2 braces.

How would I do

I get error.

if(!IsPlayerInVehicle(playerid))

[C00K13M0N$73R]

if(!IsPlayerInAnyVehicle(playerid));
or
if(IsPlayerInVehicle(playerid,vehicleid));

I think you want to check if the player is not in any vehicle not in a specified vehicleid.

pawn Код:

if(!IsPlayerInAnyVehicle(playerid))
