Determining if form has opened a record for first time

[Simon]

Hi,

I would like to determine when I open a form in my
database if it is the first time it is being accessed or
if another user has it open. If it is being editted I want
to change the caption to say as much.

s there any way to determine if a form's record is being
editted already?

Thank you for any help in advance.

Simon
