Action Sequence
On the Event Actions form, use this field to assign the order in which actions for a particular event handler are to be performed. You can assign any number you want here, and the system automatically sorts the actions in the correct sequence on the Event Handlers form. Once you save the event action, though, this field becomes display-only, and you cannot change it.
On other forms, this field is display-only.
See the About Event Actions and Controlling the Sequence of Event Handlers and Actions topics.
