If I understand, you want the time/date then a comma and then the text,
correct?
If so --
Me.Detailed_Description = Now & ", " & me.detailed_description & vbCrLf
will do that. vbCrLf is a "carriage return" and Line feed.
You will see that this is really annoying. I think what you are after is a
record of changes by the user
to be recorded in your table??? If so, I would add a field to your table as
date/time and in the after update of your form, update the field with now.
The simplest way would be to add a textbox bound to your new date/time
field,
make it invisible, and in the afterupdate event,
me.hiddenttxtbox = now
If you want to save, instead, the former contents of the textbox before
editing, that gets a bit more complex,
and you probably will want to explore audit tracking.
