How to match a specific item in a plays inventory to a master list?

Im just trying to create a scanner that scans a plays inventory, and ive got most the code down, however, I believe my code is broken because it only ever clears the player, even when the player is not supposed to be clear.

script.Parent.Touched:Connect(function(hit)
	local GateParentModel = script.Parent.Parent
	
	if hit.Parent:FindFirstChild("Humanoid") then
		local PartAlreadyFound = false
		local Player = Players:GetPlayerFromCharacter(hit.Parent)
		local Invintory = Player.Backpack
		local ItemsInInvintory = Invintory:GetChildren()
	
		for i, v in pairs(ItemsInInvintory)do
			
			for I,V in pairs(prohibitedItems) do 
				
				if v == V then
					
					IllegalItemFound = true 
					
				end
			
			end
			
		end
		
		if IllegalItemFound then
			IllegalItemVariable.Value = "true"
		else
			IllegalItemVariable.Value = "false"
		end
		
	end
	
end)

This is particularly confusing to me because I've used a similar script to this in another project, and it worked just fine there.
