Hello @v4mpthing,
Programming a donation board requires a little bit of time and stuff to handle. Therefore you need to be familiar with the basics of Lua and the built-in functions Roblox provides.
To begin with, you should know what to use in your code and keep it well-organized. The syntax may not be as significant as learning to code for a person scripting this concept, but the functionality matters here.
If you know how to code, you need to be familiar with some programmatical keywords. Here is a glossary of what you need to create a donation board with how much players spent:
DatastoreService: The place where you store how much players spent.
MarketplaceService: The service that you can prompt players to buy your gamepasses or products.
There is, of course, immense documentation on how to use APIs, and you can visit it here.
Furthermore, there are open-source code snippets that may help other developers when they don’t seem to understand the concept, and it goes beyond the topic. These articles will definitely clarify it for you and they will come in handy:
