Time Stop:GunGame How to use Kaycode to change the size?

I am creating a Time stop game but I need to use key code my script is currently:

local UIS = game:GetService("UserInputService")
local plr = game.Players.LocalPlayer
local hum = plr.Character:WaitForChild("Humanoid")

UIS.InputBegan:Connect(function(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Keyboard then
		print("Key:",input.KeyCode)
		wait(1)
		if input.UserInputType == Enum.KeyCode.T then

		print("T was pressed at", input.Position)
		local Timestop = workspace:WaitForChild("Timestop")

		repeat	

			Timestop.Size = Vector3(Timestop.Size+1, Timestop.Size+1, Timestop.Size+1)
			wait(0.1)

		until Timestop.Size == Vector3(190, 190, 190)

	end
	wait(60)

	end
end)

and I have it in Starter Character Scripts

The only output I am getting is ? Key: Enum.KeyCode.T - Client - LocalScript:7

Any help?

I noticed two errors. When you want to change the size of a 3D object it should be written as:

object.Size = Vector3.new(x,y,z) -- Value you want

Also I noticed that the if statement was wrong, you shouldn't check the enum, you should check the name or value of the keycode.

So the code should look like this:

local UIS = game:GetService("UserInputService")
local plr = game.Players.LocalPlayer
local hum = plr.Character:WaitForChild("Humanoid")

UIS.InputBegan:Connect(function(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Keyboard then
		print("Key:",input.KeyCode)
		wait(1)
		if input.KeyCode.Name == "T" then  -- https://create.roblox.com/docs/reference/engine/enums/KeyCode
			print("T was pressed at", input.Position)
			local Timestop = workspace:WaitForChild("Timestop")
			repeat  
			Timestop.Size = Vector3.new(Timestop.Size.X + 1 , Timestop.Size.Y + 1, Timestop.Size.Z + 1)
			task.wait(0.1)
			until Timestop.Size == Vector3.new(190, 190, 190)
			task.wait(60)
		end
	end
end)
