Anyone know how to fix this? -Racing script.

**I need it to be so if they haven't joined the race yet, it will add there name to a stringvalue, but if they are already in the race (with there name in a stringvalue) it simply does nothing or prints "In Race" the problem I am having is if one string value has text in it, even if it is not there name, it will not add there name to any of the string values. Please help? **

plr = game.Players.LocalPlayer.Name
script.Parent.MouseButton1Click:connect(function()
v = game.Workspace.Boards.Racing
if v.Two.Value == plr or v.One.Value == plr or v.Three.Value == plr then
	print'inrace'
elseif v.One.Value == "" then
	v.One.Value = plr
if v.Two.Value == plr or v.One.Value == plr or v.Three.Value == plr then
	print'inrace'
elseif v.Two.Value == "" then
	v.Two.Value = plr
	if  v.Two.Value == plr or v.One.Value == plr or v.Three.Value == plr then
		print'inrace'
	     elseif v.Three.Value ==  "" then
		v.Three.Value = plr
	end
end
end
end)
