Creating A Data Entry Form With A Subform
From NeoWiki

Creating the Form
The data entry form the birder will use on return from a field trip must allow for data entry into two different tables: The Field_Trips table and the Sightings Table. For every record in the Field_Trips table, there will be multiple entries in the Sightings table. So we need to create a form based on the Field_Trips table with a sub-form based on the Sightings table.
- Open the database document
- Click on the Forms icon in the left column of the main database document window
- In the Tasks section, click on Use Wizard to Create Form...
- In the Tables or Queries drop-down, choose Table: Field_Trips
- Click on the >> button to move all the field over
- Use the up or down arrow buttons to change the field order if need be
- Click Next>
- Check the Add Subform checkbox
- Click in the Subform based on existing relation radio button
- Select Sightings in the box next to the question Which relation do you want to use?
- Click Next>
- Note that the correct table is chosen in the drop-down
- Click the >> Button to move all the fields over
- Use the up or down arrow buttons to change the field order if need be
- Click Next>
- Choose the Arrangement of the main form I chose the option furthest to the right, labeled In Blocks-Labels Above
- Choose the Arrangement of the subform I reccommend the third option, labeled As Data Sheet
- Click Next>
- Set the Data Entry Mode. I set it for This form is to display all data and left all the boxes unchecked.
- Click Next>
- Select the background color and style you want.
- Click Next>
- Enter the name of the form (I chose Field Trips Data Entry) and decide if you want to work with it (i.e. enter data) or modify it (i.e. edit the layout).
- Click Finish
Entering Data
If you are creating this database as you follow the tutorial, you will need to enter data into this form, for use in future exercises. Enter the following data for two field trips.
