In an edit form is there a way to make 'read-only' applicable only to fields that have no value already entered.
Generally I have have clients enter data over a few periods, ie a preliminary stage and then final. There is however no consistency in what is presented in preliminary to final stage, thus can't just create two forms. Basically I don't want clients to be able to edit existing data, but add to fields where they have not previously added data.
I have tried working with form display 'show/hide' rules but not effective. Multiple forms on a page and rules getting too clunky. I guess I can add new fields to create true/false calc against each existing field, but this is going to expand my object considerably.
