I'm creating a workflow. The first two states are Draft and Reviewer(s). The Reviewer(s) property is multi-select. I require the user of the workflow to enter at least two Reviewer(s). I set the property pre-condition to check if Reviewer(s) > 1. However, this doesn't seem to work. I guess the ">" operator is used for numbers only, and not quantity.
Is there a way to accomplish this without creating two different properties?
