Detecting NPCS only detects the last npc in folder?

local Player = game.Players.LocalPlayer
local NPCS = game.Workspace:WaitForChild("NPCs")
local UIS = game:GetService("UserInputService")
local DetectedNPC = nil

UIS.InputBegan:Connect(function(key)
	if key.KeyCode == Enum.KeyCode.E then
		print("Pressed E")
		if DetectedNPC then
			print("Pressed E with npc nearby")
			game.Workspace.Events.DisableNPC:FireServer(DetectedNPC)
			DetectedNPC = nil
		end
	end
end)

while wait() do
	for _, npc in pairs(NPCS:GetChildren()) do
		if (npc.HumanoidRootPart.Position - Player.Character.HumanoidRootPart.Position).magnitude < 15 then
			print("NPC Detected")
			if npc.Enabled.Value == true then
				npc.UpperTorso.EToGift.Enabled = true
				DetectedNPC = npc
				print(DetectedNPC)
			else
				npc.UpperTorso.EToGift.Enabled = false
				DetectedNPC = nil
			end
		else
			npc.UpperTorso.EToGift.Enabled = false
			DetectedNPC = nil
		end
	end
end

So i have this piece of code to loop through a folder with npc's in it. It checks if the player is in range and then checks if they pressed "E". But it only detects if you press e if you are next to the npc that is the last one in the folder. Any ideas?
