You can add subform objects to a choice subform set or remove subform objects from a choice subform set in using either of these methods:
• Manually editing the contents by dragging subform objects into or out of the choice subform set by using the Hierarchy palette.
Caution: Removing a subform from the Alternative Subforms list by using the Edit Data Nominated Subforms dialog box completely removes the subform object from your form design. If you want to preserve the subform object but remove it from the choice subform set, you must manually drag the subform object out of the choice subform set by using the Hierarchy palette.
3. Click the Add button to insert a new Alternative Subforms list item. You can also drag and drop subform objects into the choice subform set by using the Hierarchy palette.Adding a new subform adds a duplicate of the currently selected subform. If no subform is selected, a new unnamed subform is added to the choice subform set.
4. Use the Up and Down buttons to move the new subform entry to the preferred location. Ordering entries in the Alternative Subforms list is important because entries are processed sequentially at run time, and the first entry with an expression that evaluates to true appears in the form.
