How would you go about changing Leaderstats Values in FE?

I am working on a shop gui, and everything works except the stats dont actually change, and it shows it just for the player.

This is what i got so far:

The layout is like this: Button > Server Script, Local Script, and Remote Event (They are all inside the button)

Local Script:

local BuyEventOn = script.Parent:WaitForChild("BuyEvent")

local Player = game.Players.LocalPlayer
script.Parent.MouseButton1Down:Connect(function(click)

if Player:WaitForChild("leaderstats"):FindFirstChild("Money").Value > = script.Parent:WaitForChild("Cost").Value and Player:FindFirstChild(script.Parent.Name).Value == 0 then

BuyEventOn:FireServer()
print("1")
end
end)

Server Script:

local BuyEventOn = script.Parent:WaitForChild("BuyEvent")

local function BuyEvent1(Player)
print("2")

Player:WaitForChild("leaderstats"):FindFirstChild("Money").Value = Player:WaitForChild("leaderstats"):FindFirstChild("Money").Value - script.Parent:WaitForChild("Cost").Value

Player:FindFirstChild(script.Parent.Name).Value = 1
script.Parent.BackgroundColor3 = Color3.new(0, 255, 0)
end
BuyEventOn.OnServerEvent:Connect(BuyEvent1)

But what im wondering is how i would change the values to be compatible with fe. If you can help then please do! Thanks!
