This script for my DevProduct gui works fine in studio, but not in-game. What's wrong with it?

So, basically. This is just supposed to be a simple to use DevProduct gui. The player gets a gui, places it in the Y position they want and the script will do the rest. Anyway, the script works well in studio, however when I test it in game, it only works for the first one.

Here is what happens...

In studio

In a server

Anyway, without any further due, here's the script:

for i,v in pairs(script.Parent:GetChildren()) do
    local player = game.Players.LocalPlayer
    if v:IsA("TextButton") then
        v.MouseEnter:connect(function()
            v:TweenPosition(UDim2.new(1,-200,v.Position.Y.Scale,v.Position.Y.Offset),'In','Sine',0.3,true)
        end)
        v.MouseLeave:connect(function()
            v:TweenPosition(UDim2.new(1,-50,v.Position.Y.Scale,v.Position.Y.Offset),'In','Sine',0.3,true)
        end)
        v.MouseButton1Click:connect(function()
            game.MarketplaceService:PromptProductPurchase(player,tonumber(v.Name))
        end)
    end
end

I also tried this:

for i,v in pairs(script.Parent:GetChildren()) do
    local player = game.Players.LocalPlayer
    if v:IsA("TextButton") then
        v.MouseEnter:connect(function()
            v:TweenPosition(UDim2.new(1,-200,v.Position.Y.Scale,v.Position.Y.Offset),'In','Sine',0.3,true)
        end)
        v.MouseLeave:connect(function()
            v:TweenPosition(UDim2.new(1,-50,v.Position.Y.Scale,v.Position.Y.Offset),'In','Sine',0.3,true)
        end)
        v.MouseButton1Click:connect(function()
            game.MarketplaceService:PromptProductPurchase(player,tonumber(v.Name))
        end)
    end
end

But I still got the same result.
