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?
