checked = script.Parent.Checked
local player = script.Parent.Parent.Parent.Parent.Parent
ranking = {workspace.Values.Line.First, workspace.Values.Line.Second, workspace.Values.Line.Third, workspace.Values.Line.Fourth}
open = false

script.Parent.MouseButton1Down:connect(function(p)
for i,v in pairs (ranking) do
if open == false then
if ranking[1].Value ~= player.Name and ranking[2].Value ~= player.Name and ranking[3].Value ~= player.Name and ranking[4].Value ~= player.Name then
checked.Value = true
open = true
script.Parent.Text = "CLICK AGAIN TO LEAVE LINE"
else 
if ranking[1].Value == player.Name then ranking[1].Value = ""
elseif ranking[2].Value == player.Name then ranking[2].Value = ""
elseif ranking[3].Value == player.Name then ranking[3].Value = ""
elseif ranking[4].Value == player.Name then ranking[4].Value = ""
