help with no Fly Zone script

[wozzsta 16]

Hi guys, 

 

i am adapting a no fly zone script i found. 

 

i have a trigger with the condition of:

"Any player - Present"

 

And the on activation: 

{ nul=["_x", "noFly1", "nf1"] execVM "airDamage.sqf" } forEach thisList;

 

this calls this script: 

 

params ["_x", "_noFly", "_oaMarker"];

switch _noFly do {

	case "noFly1" : {
	
		private ["_playersinOA"];
		
				_playersinOA = _oaMarker call fnc_playersinOA;
				["<t color='#ff0000' size = '0.8'>Warning! You are in a no fly zone!<br />Turn back now!</t>",-1,-1,6,1,0,789] remoteExec ["BIS_fnc_dynamicText",_playersinOA,false];
				sleep 5;

				_unit = _this select 0;
				_veh = vehicle _unit;
				_pos = getPos _unit;
				
				if ( _veh isKindOf "Air" && (_pos select 2) > 5 ) then {
				if (local _unit) then {
				_veh setDamage 1;
			};
		};
	};	
};

 

but when it gets to the _unit,  _veh and _pos variables it breaks: 

15:16:57 Error in expression <leep 5;

_unit = _this select 0;
_veh = vehicle _unit;
_pos = getPos _unit;

if >
15:16:57   Error position: <vehicle _unit;
_pos = getPos _unit;

if >
15:16:57   Error vehicle: Type String, expected Object

 

 

any ideas what i can do to fix it? im lost? 

 

Thanks.
