Okay i'm trying to remove objective marker after making it. But its not working. in my system, when a player buys a car, objective marker shows where it has spawned and objective marker SHOULD disappear when player enters vehicle. I can make Marker but i cant destroy it. This is what i am writing

SetVehicleParamsForPlayer(Id,playerid,0,0);

I've tried making a command which sets objective parameter to 0 for every vehicle in game. but still it doesnt works.
btw i'm creating markers in OnVehicleStreamIn.

Any help?
