whenever I click a object with a clickdetector how do I found out who clicked it?

I don't really know how to do this but I want to be able to click the item then it copies the players name into the items StringValue

I don't have a script yet because I don't know how to start really

The variable 'plr' is the actual Player.

script.Parent.ClickDetector.MouseClick:connect(function(plr)
	print(plr.Name)
end)
