A report may also be an option. Can you help out?

Come to think of it, Jeff has the right idea. Simply add a field to your
table, DataType AutoNumber, and make it the primary key, and make sure its
primary property is set to yes. That will number anything you want. The only
caveat, as Jeff points out, is that if there's no rhyme or reason to the
order, you night have to do some re-numbering manually.

If you'd rather do the report, make your report as you would normally. Then
add an unbound textbox (call it say txtMyCount), and initialize it to count
for you, as follows:

Make a global variable, MyCount, type Long. In the Open event of your report,
initialize MyCount = 0. In the Detail OnPrint event, have the following code:

MyCount = MyCount + 1
Me.txtMyCount = MyCount

Either way will work.
