Why isn't this conditional statement work properly?

For some reason line 17 won't run at all,why?

local BlueBar = script.Parent.GAME.BluPdl
local RedBar = script.Parent.GAME.RedPdl
local BlueSeat = script.Parent.Parent.Parent.Parent.BlueSeat
local RedSeat = script.Parent.Parent.Parent.Parent.RedSeat
----------------------BlueSeat----------------------------
BlueSeat.ChildAdded:connect(function(Part)--Checks if a Player has been steated
	if Part.Name == "SeatWeld" and Part.Part1.Name =="HumanoidRootPart" then
	---------------------Vairbles-------------------------
	local Character = Part.Part1.Parent
	local Player = game.Players:GetPlayerFromCharacter(Character)
	local PlayersMouse = Player:GetMouse()
	------------------------------------------------------
	PlayersMouse.KeyDown:connect(function(Key)
			if Key == "w" then
				if BlueBar.Position.Y.Offset > 0 then -- Rise Up if pressed w
					BlueBar.Position = UDim2.new(0, 0, 0, (BlueBar.Position.Y.Offset - 20))
				elseif Key == "s" then
					print("hi")--Test
				end
			end
		end)
	end
end)

I was testing if I did something wrong and made another script and it works but the one above won't and there almost the same.

Seat = script.Parent
	Seat.ChildAdded:connect(function(Part)
		if Part.Name == "SeatWeld" and Part.Part1.Name =="HumanoidRootPart" then
			Character = Part.Part1.Parent
			Player = game.Players:GetPlayerFromCharacter(Character)
			PlayersMouse = Player:GetMouse()
				PlayersMouse.KeyDown:connect(function(Key)
				if Key == "s" then
					print(Key)
				end
			end)
		end
	end)
