Attaching Formulas to List Names

Attaching a Formula to a List Name
You can attach a formula to a list name so that each list element is a result of the formula. When
executed, the attached formula must resolve to a list.
When anything in the attached formula changes, the list to which the formula is attached is
updated automatically.
• When you edit an element of a list that is referenced in the formula, the corresponding element
in the list to which the formula is attached is updated.
• When you edit the formula itself, all elements in the list to which the formula is attached are
updated.
