Build yourself a table with fields like [LastName] and [FirstName].  One of
your fields can be [Printed] and it should be a “Yes” or “No” combo.

Now built the report.  The report should look like your certificate.  A Text
Box in your report could be [FirstName]&” “&[LastName]

The report could be built off of a query or use the SQL Statement Query
Builder to tell the report to print only the certificates that you have
selected.

Hope that makes sense to you.

The one I am doing is quite complicated. I will give you the basic tables to
help get you started. This is a many-to-many relationship since each employee
can attend many classes and each class can have many employees:

tble_booking
BookingID (PK) Autonumber)
RoomID
CourseID
Duration
Trainingdate
TrainingTime
SupervisorID

tble_employee
EmployeeID (PK)
Employee

tble_attend
EmployeeID (FK)
BookingID (FK)
Attendance

1) Put the Booking table fields in the main form

2) Put "EmployeeID" and "Attendance" from "tble_attend" in the subform.
"BookingID" will be linked from the main form.

3) In the subform make the "employeeID" a combo box and use "tble_employee"
as the source. Make the ID number the bound column (in the data tab) but show
the names by making the width of the first column "0cm" and width of the
second column "2cm" (column widths in the format tab). This will show the
name but store the ID number.

The attendance field is a checkbox. After the training has finished, the
supervisor can tick all those who attended and then you can calculate
attendance rates.

What you can also put on the main form is a button that will open an
attendance register report. Base the report on a query that restricts the
report to the training course field on the main form.

That is the very basic one. Mine has forms for supervisors, courses,
department and employee information and employee feedback questionnaires.
