For a very specific situation, I need to save in a field, the phases through which a budget goes through, discarding certain phases.

Field 1 to field 2.

This so that later, with another field 2 trigger, it can record again in field 1, the last phase that was saved.

I have tried with a function, testing variables in various ways, but the value is not saved from field 1 to field 2.

More information, the configuration of field 1 is multiple choice. I don't know if this is the problem. But I have sent this type of data between different modules before.

Any idea what I'm doing wrong?
