Preceding Rule - Using the Add / Edit Rule Dialog

The Add/Edit Rule dialog allows the user to build a rule expression that is evaluated before the activity instance is started. Multiple rule expressions can be added. The Rule is evaluated using the following formula: [First Variable] [Comparison Operator] [Second Variable] = Result
