Brian,
Make a query that contains only the data on page three. Its
criteria should be that the primary key equals
=Forms![YourPageThreeForm]![YourKey]
Base a report on that query.
Put a command button on Page 3 or wherever and launch the
report.
Alternatively, you can base a report on the page three data.
Then when the command button is clicked you can specify the
criteria as:
"[YourPrimaryKey] = '" & Forms![YourPageThreeForm]![YourKey] & "'"
In this case YourKey is alphabetic, not numeric.
You can also search here for OpenReport for examples.
