How do i weld a hat onto a head?

I'm new to scripting, so i cant really code without help. I'm trying to put a hat on a character... Explorer Code:

while true do
	game.Workspace.Crimson.Handle.Weld.Part0 = game.Workspace.Crimson.Head
	game.Workspace.Crimson.Handle.Weld.Part1 = game.Workspace.Crimson.Handle
end
