[SOLVED] Currency isn't saving after purchase. Can someone help?

So i have a button and when you click it it changes a value to something else. When i rejoin the game the value is the same as it was before but if i change the value through developer console it does save. Please help!

here is the server script inside the button:

local Player = script.Parent.Parent.Parent.Parent.Parent.Parent
local LS = Player:FindFirstChild("leaderstats")
local Button = script.Parent
local Image = script.Parent.Parent
local CharVal = Player:WaitForChild("CharacterValues"):WaitForChild("Jessica")

Button.MouseButton1Click:Connect(function()
	if CharVal.Value == 1 then
		script.Parent.Equip.Disabled = false
		LS.Character.Value = "Jessica"
		Button.Text = "Equipped"
		
		wait(3)
		script.Parent.Equip.Disabled = true
	elseif CharVal.Value == 0 then
		script.Parent.Purchase.Disabled = false
		CharVal.Value = 1
		LS.Character.Value = "Jessica"
		Button.Text = "Equipped"
		LS.Bucks.Value = LS.Bucks.Value - 300
		
		wait(3)
		script.Parent.Purchase.Disabled = true
	end
end)
