I am trying to gather interest for sponsorship for an event. We have different levels and categories. We need one sponsor for each sponsorship request, so we need to limit how many people can select a particular level. For example, looking for sponsors for the below - only one person per item.
Item 1 - Trip to Boston
Item 2 - Car
Item 3 - Designer Shoes
We need one sponsor for each, once a participant goes in and says they will sponsor that item, we want the answer choice to either disappear or become unselectable. Any tips on how to accomplish this?
