My shop and rebirth scripts arent working!?

`Cost = game.player.leaderstats.rebirths.Value + 1 * 10 * game.player.leaderstats.rebirths.Value + 1 * 10000 * 100 * game.player.leaderstats.rebirths.Value + 1 * game.player.leaderstats.rebirths.Value + 1 * 2

script.Parent.Text = "Rank Up Costs: "..Cost Cost.Changed:connect(function() script.Parent.Text = "Rank Up costs: "..Cost end rebirths = game.player.leaderstats.rebirths.Value multiplier = game.player.leaderstats.rebirths.Value * game.player.leaderstats.rebirths.Value + 1 * 10 * game.player.leaderstats.rebirths.Value + 1 * game.player.leaderstats.rebirths.Value + 1 * 2

script.Parent.MouseButton1Click:connect(function()

if points >= cost	
then rebirths = rebirths + 1	
	points = 0
	game.player.leaderstats.multiplier.value = game.player.leaderstats.multiplier.value + 1 + multiplier
	 

else
	end
	     end))` is my rebirth script then my shop script `Amount = game.player.leaderstats.timesbought.Value + 100 * 3 / 3 + 1 / game.player.leaderstats.rebirths.Value + 1 / game.player.leaderstats.rebirths.Value + 1 / game.player.leaderstats.rebirths.Value + 1 * 2 / 5 + 10 

script.Parent.Text = "Buy clicks for: "..Amount amount.Changed:connect(function() script.Parent.Text = "Buy clicks for: "..Amount points = game.player.leaderstats.points.Value clicks = game.player.leaderstats.clicks.Value clicksgained = game.player.leaderstats.timesbought.Value / 100 + 1 * game.player.leaderstats.rebirths.Value + 1 * game.player.leaderstats.rebirths.value timesbought = game.player.leaderstats.timesbought.Value

script.parent.Mousebutton1Click:connect(function() if points >= Amount then points = points - Amount clicks = clicks + clicksgained

end end)`
