I am creating an app for a conference. Each seminar is assigned a code -- such as 101, 102, 103, etc. -- and the app will automatically create signage and displays for us. One of the services I want to provide is to tell people not only what seminar takes place right now, but which seminar will be *next up* in a particular ballroom. I have created a field called Next, into which we would enter the code for the seminar that takes place next, but that's as far as I have gotten. How do I automatically gather the information?
For instance, let's say that Seminar 101 is entitled "How to Think," and is being led by John. Next up in that room is Seminar 103, entitled "How to be Great," led by Jane. I want to create a calculated field that would be part of 101's record that would automatically pick up title and speaker from 103's record.
How would I do that??
