Is this script correct?

H = game.Workspace.Part
function onTouch(thing)--Thing is the thing that touched this part
wait(2)
H.Transparency = 1
wait(2)
H.Transparency = 0 -- Changing the transparency of H, which is the part in workspace.
end
script.Parent.Touched:connect(onTouch)--The most important part, the closing of the function. This calls the function when the script's parent is touched. Make sure that this script is inside of the object you want to be touched.

game.Workspace.Part

function OnTouch(Part)
wait(2)
game.Workspace.Part.Transparency = 1
wait(2)
game.Workspace.Part.Transparency = 0
end
