I’m editing a task form in my workflow. I want a custom field called “Comments” to show if the user selects the “Reject” option for the outcome. Normally I would do this by adding my custom field to the form and then for the “Visible” property set it to something like Form.Outcome == “Rejected”. But I can’t get this to work. The Form.Outcome control is missing!!

Why is the “Outcome” control missing from here and how can I make rules when I can’t see it??
