Script searching for a value inside of an Accessory even though It isn't suppose to?

This script searches for "LogiaImmune" inside of an Accessory when it hits an Accessory, even though it isn't suppose to. I get this error message, when I shouldn't. Any idea why?

Script:

r = game:service("RunService")
arrow = script.Parent
 a = Instance.new("Sound")
        a.SoundId = "http://www.roblox.com/asset/?id=137463821"
        a.Parent = arrow
a.Volume = 2
a:play()
Owner = arrow.Owner
torso = game.Workspace:FindFirstChild(Owner.Value.Name).Torso
damage = 2
position = arrow.Position

function fly()
	direction = arrow.CFrame.lookVector 
	position = position + (direction*6)
	error = position - arrow.Position
	arrow.Velocity = error * 50
end

function onTouched(hit)
if hit.Parent.Name ~= Owner.Value.Name and hit.Name~="Part" and hit.ClassName~= ("Accessory") and hit.Name~= "Blast" and hit.Name~= "Damage" then
	humanoid = hit.Parent:findFirstChild("Humanoid")
	t = hit.Parent:FindFirstChild("Torso")
	if humanoid~=nil then
     if humanoid.Parent:findFirstChild("Logia") == nil or humanoid.Parent:findFirstChild("Logia").Value == false and humanoid.Parent:findFirstChild("ForceField") == nil then
		humanoid.Health = humanoid.Health - damage
		 t.Velocity = torso.CFrame.lookVector * 80 + Vector3.new(0, 0, 0)
	end
     if arrow.Name == "HakiPowered" then
		humanoid.Health = humanoid.Health - damage*2
        humanoid.Sit = true
        wait()
        humanoid.Sit = false
        humanoid.Jump = true
end
wait()
end
end
end

function SmokeHit(hit)
if hit.Parent.Name ~= Owner.Value.Name and hit.Name~= "Blast" and hit.Name~= "Damage" and  hit.ClassName~= ("Accessory")and  hit.Parent:WaitForChild("LogiaImmune").Value =="Smoke"  then
	humanoid = hit.Parent:findFirstChild("Humanoid")
	
local EffectTorso = game.ReplicatedStorage["Plume-PlumeParticle"]:Clone()
			EffectTorso.Parent = hit.Parent:FindFirstChild("Torso")
			local EffectLArm = game.ReplicatedStorage["Plume-PlumeParticle"]:Clone()
			EffectLArm.Parent = hit.Parent:FindFirstChild("Left Arm")
			local EffectRArm = game.ReplicatedStorage["Plume-PlumeParticle"]:Clone()
			EffectRArm.Parent = hit.Parent:FindFirstChild("Right Arm")
			local EffectLLeg = game.ReplicatedStorage["Plume-PlumeParticle"]:Clone()
			EffectLLeg.Parent = hit.Parent:FindFirstChild("Left Leg")
			local EfectRLeg = game.ReplicatedStorage["Plume-PlumeParticle"]:Clone()
			EfectRLeg.Parent = hit.Parent:FindFirstChild("Right Leg")
			
			
			game.Debris:AddItem(EffectTorso, 1)
			game.Debris:AddItem(EffectLArm, 1)
			game.Debris:AddItem(EffectRArm, 1)
			game.Debris:AddItem(EffectLLeg, 1)
			game.Debris:AddItem(EfectRLeg, 1)
				
	
script:remove()   
end
wait()
end


arrow.Touched:connect(onTouched)
arrow.Touched:connect(SmokeHit)

t, s = r.Stepped:wait()

d = 1 + 0 - 1

while t < d do

end

wait(2)
arrow.Parent:Remove()

The part where the error would be coming from is line 42.

Thanks for reading <3

You should put another if statement after line 42 where it looks for the value. It probably still reads the value part even though it failed the check if it was an accessory. Also, :Remove and :remove is deprecated, use :Destroy(). :wait() is deprecated, use :Wait(). connect is deprecated, use :Connect.:service is deprecated, use :GetService(). You also never created the debris service, so do game:GetService('Debris'). Also, please indent properly. Edit: :findFirstChild is deprecated, use :FindFirstChild.
