There is a problem with this tycoon door script?

I get this in the output: OwnerName is not a valid member of Model and this is the script it is a tycoon door. Whenever I go on it nothing happens it just stays and no words change or anything

script.Parent.Head.Touched:connect(function(hit)
    chr=hit.Parent
    if chr:findFirstChild("Humanoid") and game.Players:GetPlayerFromCharacter(chr) then
        plr=game.Players:GetPlayerFromCharacter(chr)
        if not plr.hastycoon.Value then
            plr.hastycoon.Value=true
            script.Parent.Parent.OwnerName.Value=plr.Name
            script.Parent:remove()
        end
    end
end)
