I'm using the writeback form, adding a field into the form for user reference. The field can have multiple entries, so I am using text area and an aggr to get all the entries. =Concat(Aggr([field],[Line]),chr(10)&chr(13)).
It would be nice to be able to sort this field, and also be able to have more than 20 lines in this area.
sorting is possible in aggr (or even better in the script) so this should already be possible. I have requested a bit more information in PM to see if we can sort out an example.
