It sounds like you're trying to insert multiple dates into a single date field. That won't work, because FileMaker automatically validates any entry to see that it's a valid date.
I think you need to adjust your data model. You should have a related table of dates, with the relationship sorted by date in descending order. Then, the first related record will be the most recent date.
Of course, I'm not sure what you mean by a "repeating function", either ...
Mike—thanks I’ll try it—Im a physicist not a programmer, but all jobs change——make a table with any dates that can change and put them in descending order---OK—I kept getting hung up when you connect the “wires” to form the relationship, how to see or display the resultant field??
how to see or display the resultant field??
Can you explain a bit more what you mean by this?
sorry, Im very new to this----when I connect to combine the static data fields in relationships to the new table with dates in descending order that are being updated, the combination of the two tables is...where??---
