I would like to develop a webpage for a blind raffle. That is the kind of raffle where the amount donated is chosen randomly from a set of number, eg. 1-200. Please see here for example - https://www.rayze.it/dealcamp/
I would like the page to be setup so it can be reused as many times as needed for many consecutive raffles over the course of several years. Each time the number set will need to be changed through a backend input.
