One irritation in using subform controls is having to create the form used as the subform. Although it's not the most advanced topic, using the Subform/Subreport Wizard can save a great deal of time and hassle. Rather than create the form used as a subform or subreport ahead of time, follow these steps:
Create the main form as you normally do.
While still in Design view on the main form, make sure that the wizards are toggled on by using the Wizard control in the toolbox.
Click the Subform/Subreport control. The first dialog of the SubForm Wizard appears (see Figure 10.28).
