My Inventory System adds multiple items and not just one, why is that?

Basically, I have got the Inventory System to work pretty darn well. When the player presses E on their keyboard the item is then removed from the world and put into their inventory. The problem is that when the item is picked up, multiple quantitys of that time is added and not just one. It should add 1 item and not like 6.

local player = game:GetService("Players").LocalPlayer
local char = player.Character
local mouse = player:GetMouse()
local inv_gui = script.Parent.Inventory
local inv = player:WaitForChild("Inventory")

while wait(0.1) do
	for _,item in pairs(workspace["WinterSurvival"].DroppedItems:GetChildren()) do
		if (item:IsA("Model")) then
			local itemID
			function findID(par)
				for _,kid in ipairs(par:GetChildren()) do
					if (kid:IsA("Model")) then
						itemID = kid.ItemID.Value
					else
						findID(kid)
					end
				end
			end
			findID(game:GetService("ReplicatedStorage").Items)
			local label = script.Parent.PressE
			if (char:FindFirstChild("Torso").Position - item.Handle.Position).magnitude < 7 then
				label.Text = "Press [e] to pick up '"..item.Name.."'"
				label.Visible = true
				local debounce = true
				mouse.KeyDown:connect(function(key)
					if (key:lower() == "e" and debounce) then
						debounce = false
						for _,slot in pairs(inv:GetChildren()) do
							if (slot.ItemID.Value == itemID) then
								slot.Qty.Value = slot.Qty.Value + 1
								label.Visible = false
								item:Destroy()
								break
							else
								if (slot.ItemID.Value == 0) then
									slot.Qty.Value = 1
									inv_gui[slot.Name].Qty.Visible = true
									slot.ItemID.Value = itemID
									slot.Value = item.Img.Value
									label.Visible = false
									item:Destroy()
									break
								end
							end
						end
					end
					debounce = true
				end)
			else
				label.Visible = false
			end
		else
			return
		end
	end
end

on line 27, change

and debounce

to

and debounce == true

this should fix things.

Why should this work?

well, when you say; "if value then" you're saying "if this value is not Nil then do this", now, false isn't nil, it's an actual value, so you have to say either "if value == true" or "if value ~= false" to get the desired result, depending on how strict you want to be with the script.
