This script is to give the player 100 coins when they buy the developer product, but I have another developer product for 5000 coins but I want to do the same to the 500 coins developer product as I did to the 100 Coins developer product. But it’s not working.

Just add a new item to the productsGold table for each product. The index will be the product id and the value will be a table with a index “reward” with a value that is the amount of gold that you want to give the player.
