How do you change the value of a variable outside of your script?

I'm trying to make it so that whenever touch pad is touched, the script finds the players name and assigns it to the Owner StringValue and then prints the owners name. So far it prints the owners name, however the Owner StringValue remains unchanged. What am I doing wrong?

local touchpad = Tycoon.Entrance.touchpad
local owner = game.Workspace.Tycoon.Owner.Value

	local function steppedOn(part)
	local player = part.Parent
		if game.Players:GetPlayerFromCharacter(player) then
		local player = game.Players:GetPlayerFromCharacter(player)
		owner = player -- Supposed to make the Owner.Value equal to the player
		print(owner)
	end
end

touchpad.Touched:connect(steppedOn)

Thanks
