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
