Beautiful, Thank You. Rob

You're going to run afoul of JCAHO with this approach, to say nothing of
malpractise lawyers! In hand written notes, a health care provider cannot
remove a written note and then write another, which is essentially what
you're trying to allow them to do. They have to strike thru the old notes
with a single line and initial it, then write another note in it's place! The
only way to emulate this in online notes is to only allow notes to be emended.
The old text has to remain, with the person adding an additional note stating
something like "Correction to note of thus and such day and time."

The general way that I do this is to make the memo field itself always locked.
I mput a button next to it, call it "ADD a Note." Clicking it brings up a
text box for adding notes. The user enters their notes and DoubleClick the
note field. The note gets added to the old text, along with a date/time stamp
and the user username.

If JCAHO or an attorney comes along, you can show that the use has no means
of changing a previously entered note.

I'm 4+ busy right now, but I'll dig around and post some example back here in
a day or two, if you're interested!
