How do you move a player up, from a leaderboard?

I created a demo that will always add on:

positions = {30,60,90,120}

while wait(5) do
guiclone = script.Parent.TextLabel:Clone()
guiclone.Parent = script.Parent
guiclone.Position = UDim2.new(0,20,0,positions[1]
table.remove(positions,1)
end

So this script works, but my issue is that when the player leaves the button disappears, but the buttons with playernames on them don't move up when the player leaves. I haven't resolved this issue as I don't have any way of finding out how to fix it. Help please!
