I have a form with 5 fields. One or all 5 may have text data in them. Then on the form I also have a field that I want to combined the data from the 5 (or less) field into separate with a comma and a space.
So if for example field 1 has "Green", field 2 has "Orange", and field 3 has "Purple", then the combined field would read... "Green, Orange, Purple"
How can I do this so that the combined field is updated after each of the other fields are updated?
