Locking previous data in a field, but enabling editing/adding dates for new entries
OK, I'll try to explain my long winded subject line...
I have a "notes' field in my resume database... I'd like to be able to 'lock' any previous notes that were added to the field, but be able to enter new notes cumulatively.
Also, is there any way to automatically insert the date and time of each new entry? I'd like to have something that looks like this:
April 19, 2009: 5:30pm <-- auto enters when I add a new note
Left message for Bob, re: engineering position <-- can't modify or delete once entered
April 20, 2009: 3:21pm
Bob called me back, interested in position, sending me updated resume
Any thoughts on how this could be done?
