I have a data entry form based on a table. I want it to open for only the top (or most recent) 75 or so records based on the autonumber field or date field for greater speed. I don't need all my 12,000 or so records available here. I want this done automatically when the form is opened. Ideas?

If you are concerned with performance, you will need to make the field (autonumber or date) an index.
Then, you can make your form's records source an sql queyr such as:
SELECT TOP 5 * FROM TheTable ORDER BY AutonumberFieldName
You could also do something like this:
Select * from TheTable where ModifiedDate >= Today - 7
for information modified in the last week.
of course, you would want to add a modified date field to your recordset, make it an index.
To set the modified date, use the form's BeforeUpdate property, add an invisible control to contain the modified date, and assign 'now' to the control, e.g.
private sub Form_BeforeUpdate
me.ModifiedDate = now
end sub
