====== What link opened the page? ======
This evaluation will pass if the selected link field opened the current page, and will fail if the page was opened by a different link.
===== Explanation =====
Evaluations have two [[Automation Trigger|automation triggers]] associated with them : Then and Else.  Actions under the "Then" automation trigger execute when the evaluation passes, and actions under the "Else" automation execute when the evaluations fails.

Form opened by evaluations are used to execute a set of actions if the current page was opened by a certain link field, and another set of actions if a different link field opened the page.

Example : Suppose an application has a [[Form Type - List|list]] of Contact's that an Administrator User can see and another list of Contact's that non-Administrator Users can see.  These two lists have different [[Field Type - Link|links fields]] on them that both open the same [[Form Type - Page|page]], Add Contact.  On that page, a form should be shown if an administrator is viewing the page, and it should be hidden if a non-administrator user is viewing the page.  One way to accomplish this is to create a form opened by action on the "Form Security" automation trigger of the form to be effected, and under the appropriate automation trigger add a [[Action Type - Hide Form|hide form]] action.
