Problems cancelling form open

[Mitch Edelman]

I'm trying to open a form with a docmd.openform statement; in the
form open event, I trap for no records and if there are none, I
cancel the open event for this form (and give an informative message
to the user).
However, I then blow up on an error (value 2501), which seems not to
be trappable. So o o o - how does one cancel opening a form which
is opened by way of a docmd.openform action? Thanks in advance for
any information you might care to pass along.
