                format(string,sizeof(string),"This Vehicle Is Owned By Fort Carson Sheriff Dept", string);
                SendClientMessage(playerid, COLOR_LIGHTBLUE, string);
                return 1;
            }
            else
            {
                RemovePlayerFromVehicle(playerid);
                SendClientMessage(playerid, COLOR_ERROR, "ERROR: You are not a Cop.");
                return 1;
            }
            return 1;
        }
        return 1;
    }
}

RemovePlayerFromVehicle(playerid); dose not work?

pawn Код:

if (CopSkin == 280 || CopSkin == 281 || CopSkin == 282 || CopSkin == 283)
            {
                format(string,sizeof(string),"This Vehicle Is Owned By Fort Carson Sheriff Dept", string);
                SendClientMessage(playerid, COLOR_LIGHTBLUE, string);
                return 1;
            }
            else
            {
                RemovePlayerFromVehicle(playerid);
                SendClientMessage(playerid, COLOR_ERROR, "ERROR: You are not a Cop.");
                return 1;
            }
            return 1;

To this...

pawn Код:

if (CopSkin == 280 || CopSkin == 281 || CopSkin == 282 || CopSkin == 283)
            {
                format(string,sizeof(string),"This Vehicle Is Owned By Fort Carson Sheriff Dept", string);
                SendClientMessage(playerid, COLOR_LIGHTBLUE, string);
                return 1;
            }
            else
            {
                RemovePlayerFromVehicle(playerid);
                SendClientMessage(playerid, COLOR_ERROR, "ERROR: You are not a Cop.");
                return 1;
            }

I don't think you need to include the "return 1;" at the end of that if statement.

The player is only entering so he isnt in the vehicle and so he cant be removed

Also, looking at the code.

Why do you need to

pawn Код:

format(string,sizeof(string),"This Vehicle Is Owned By Fort Carson Sheriff Dept", string);
SendClientMessage(playerid, COLOR_LIGHTBLUE, string);

There are no variables in that so you can just use a regular sendclientmessage, no formatting needed...
