So this is part of a project that I’m currently working on where I needed changes to ACF fields to do a lot more than what it normally does. It won’t give you exactly what you need but the ideas are all the same.
You’ll need to create a ready function for the message field that will get the values from the other fields and show the changes. Really, in your case you’re talking about having one main function that modifies the field where things are shown and calling it whenever a change is made.
You’ll probably also want some type of hidden field as well if you want to store the results.
