Judy, I assume that each time the report is run, it reports one person.
There are some conceptual problems here: What if the person requesting the
report types in a name that doesn't match? What happens if it matches more
than one name? What if s/he's not sure of the name because others are close?
You would be much better off by using a dialog form with a combo box that
displays the User Names from the User table and lets the operator choose
one. This would allow you to use the informal name from the get-go.
A second problem is that you can't request user input from text boxes in a
report. The 2 date parameters should be added to the query that is the
recordsource for the report, or better they can be eliminated by the
operator entering them in text boxes on the form along with the User Name
combobox. Then modify the query to look at the form for the three entered
variables.
Add a command button on the form so that after the three fields are filled
in, a click event procedure could run the report.
