Constant Error when no sight attached

[schadler17 36]

Trying to get this script to basically restrict specific weapon sights based on Class.

 

It works, but when the player has NO sights, it throws an error based on the _weaponSight variable not being able to find anything..

private ["_rClass", "_rItem", "_weaponSight", "_weaponSightName"];
  
while {true} do
{
	  _rClass = _this select 0;
	  _rItem = _this select 1;

	  _weaponSight = primaryWeaponItems player select 2;
	  _weaponSightName = getText(configFile >> "CfgWeapons" >>_weaponSight >> "displayName");
  
  sleep 3;
  
	  if ((_weaponSight in _rItem)	&&   !(typeOf player in _rClass))
		
	  then {
	  
		player removePrimaryWeaponItem _weaponSight;
		
		hint format ["RESTRICTED WEAPON SIGHT\n\nYour class is not allowed\nto use %1.",_weaponSightName];

	  };
} forEach allUnits;

private ["_rClass", "_rItem", "_weaponSight", "_weaponSightName"];
 
while {true} do
{
      _rClass = _this select 0;
      _rItem = _this select 1;

      _weaponSight = primaryWeaponItems player select 2;
      _weaponSightName = getText(configFile >> "CfgWeapons" >>_weaponSight >> "displayName");
 
  sleep 3;
 
      if (!isNil _weaponSight) then //check if _weaponSight is empty
      {
          if ((_weaponSight in _rItem)    &&   !(typeOf player in _rClass)) then
          {
          
            player removePrimaryWeaponItem _weaponSight;
            
            hint format ["RESTRICTED WEAPON SIGHT\n\nYour class is not allowed\nto use %1.",_weaponSightName];

          };
      };
} forEach allUnits;

That should hopefully solve the issue.

Fixed it using:

_weaponSight = player weaponAccessories primaryWeapon player select 2;

Thanks for the help though :P
