Buttons In Pairs With Filtering Enabled?

Can someone please help me . I need to fix this script so that it works with FE. Currently when I click any button only the first button works but all the others do not.

I realize that I need different events to fire each button but I cannot figure out how to add the different events in with the buttons being in Pairs. Here is the script. Any help would be greatly appreciated.

Local Script

local SaveToDataStore = game.ReplicatedStorage.SaveToDataStore
local player = script.Parent.Parent.Parent.Parent
local money = player.leaderstats.Money

print(script.Parent.Parent.Parent.Parent)
function getPlayerById(id)
for i,v in pairs(game.Players:GetPlayers()) do
if v.userId == id then
return v
end
end
end


for _, button in pairs(script.Parent:GetChildren()) do
    if button:IsA("TextButton") then
local productId = button.Value.Value
local mps = game:GetService"MarketplaceService"
local NumValue = button.NumValue.Value

button.MouseButton1Click:connect(function()
button.Button:FireServer()
end)
    end

end

Sever Script

local SaveToDataStore = game.ReplicatedStorage.SaveToDataStore
local player = script.Parent.Parent.Parent.Parent
local money = player.leaderstats.Money

print(script.Parent.Parent.Parent.Parent)
function getPlayerById(id)
for i,v in pairs(game.Players:GetPlayers()) do
if v.userId == id then
return v
end
end
end

for _, button in pairs(script.Parent:GetChildren()) do
    if button:IsA("TextButton") then
local productId = button.Value.Value
local mps = game:GetService"MarketplaceService"
local NumValue = button.NumValue.Value
local Event = button.Button

Event.OnServerEvent:connect(function()
mps:PromptProductPurchase(script.Parent.Parent.Parent.Parent, productId)


mps.ProcessReceipt = function(info)

local plr = getPlayerById(info.PlayerId)
if plr and plr:FindFirstChild"leaderstats" and plr.leaderstats:FindFirstChild"Money" then
money.Value = money.Value + NumValue

print ("Second Time It Processes" .. NumValue)

SaveToDataStore:FireServer(money.Value)
 return Enum.ProductPurchaseDecision.PurchaseGranted        

end
end
end)
    end

end
