When the button I circled in this link is pressed, I want the gun to zoom in. How do I make this happen with the following script?

local Tool = script.Parent
a = false
cam = nil
wut = Tool.Parent



function onEquipped(mouse2)
	mouse2.KeyDown:connect(onkeyDown)
	mouse = mouse2
end
function onkeyDown(key) 
	if key == "z" then -- I don't want the zoom button to be z.
		if not a then 
			cam = game.Workspace.CurrentCamera:clone()
			cam.Parent = game.Workspace
			game.Workspace.CurrentCamera.CameraSubject = Tool.Zoom
			game.Workspace.CurrentCamera.CameraType = 1
			Tool.Recoil.Value = 5
			Tool.ZoomedIn.Value = true
			Tool.Parent.Humanoid.WalkSpeed = 10
			a = true
		else
			game.Workspace.CurrentCamera.CameraSubject = game.Players.LocalPlayer.Character
			game.Workspace.CurrentCamera:Remove()
			game.Workspace.CurrentCamera = cam
			Tool.ZoomedIn.Value = false
			Tool.Recoil.Value = 10
			Tool.Parent.Humanoid.WalkSpeed = 16
			a = false
		end
	end 
end




script.Parent.Equipped:connect(onEquipped)
