What filters or actions do I need to use and what would the function to make this happen look like? Can you give me an example?
Side note, I think I found on the forum that there is a feature request for conditional form logic (i.e. if option A is checked then show text box B). I too would like this feature, but is there a way to do this now with filters and actions similar to above? If so, can you give me an example for this as well?
