Trigger

The rule script can use the value entered for this item in performing its calculations or edit checks. However, the rule does not require a value to be in this item in order to run.

In the following example, the Frame Calc rule determines the value of the Frame item by using the values of the Gender, Height, and Wrist Circumference items, which are Dependency dependencies. The rule runs if a submit occurs and the Gender, Height, and Wrist Circumference items all contain data. The Frame item, whose value is calculated by the rule, can be blank.

Note: This type of dependency is very useful when the rule is a calculation that depends on an item that is located in a different form. By firing the rule whenever a dependent item is updated, it ensures that the calculated item is recalculated even though the submission occurs in a form other than the one the rule is attached to. If you define an association as an additional dependency, the InForm Architect application enforces Trigger as the only allowed Dependency Type.
