Ah okay

First send your code either in a picture or with this format

So for this dev product to work

Let’s see what’s wrong with it

Ideally you wanna handle it the way roblox shows

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local productFunctions = {}

-- ProductId 123123 brings the user back to full health
productFunctions[123123] = function(receipt, player)
if player.Character and player.Character:FindFirstChild("Humanoid") then
player.Character.Humanoid.Health = player.Character.Humanoid.MaxHealth
-- Indicate a successful purchase
return true
end
end

-- ProductId 456456 awards 100 gold to the user
productFunctions[456456] = function(receipt, player)
local stats = player:FindFirstChild("leaderstats")
local gold = stats and stats:FindFirstChild("Gold")

if gold then
    gold.Value += 100
    return true
end

end

local function processReceipt(receiptInfo)
local userId = receiptInfo.PlayerId
local productId = receiptInfo.ProductId

local player = Players:GetPlayerByUserId(userId)
if player then
    -- Get the handler function associated with the developer product ID and attempt to run it
    local handler = productFunctions[productId]
    local success, result = pcall(handler, receiptInfo, player)
    if success then
        -- The user has received their benefits!
        -- return PurchaseGranted to confirm the transaction.
        return Enum.ProductPurchaseDecision.PurchaseGranted
    else
        warn("Failed to process receipt:", receiptInfo, result)
    end
end

-- the user's benefits couldn't be awarded.
-- return NotProcessedYet to try again next time the user joins.
return Enum.ProductPurchaseDecision.NotProcessedYet

end

-- Set the callback; this can only be done once by one script on the server!
MarketplaceService.ProcessReceipt = processReceipt

You can find more here

You can pretty much just copy and paste this script

And change the productID

And put the function that adds the 100 jump power

As for it not showing up… there doesn’t seem to be an issue on the server side

Just make sure you’re doing this alright

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local player = Players.LocalPlayer

local productId = 0000000 -- Change this to your developer product ID

-- Function to prompt purchase of the developer product
local function promptPurchase()
MarketplaceService:PromptProductPurchase(player, productId)
end

That should basically be it
