Hi,

 

I would like to make a field mandatory, but only when a certain selection is made within another field (a choice drop down). i.e. if the choice drop down states "X to Y", it prompts a person field to become mandatory. 

 

Hope that makes sense and is a simple rule. 

 

Thanks, Andy. 

Which forms designer are you using? You can use a rule to accomplish this in either the Responsive or Classic designer.



 



Follow these steps in the Responsive designer:





  1. Add a rule to the person field.


  2. Configure the rule with these options:



    1. Rule Name = Require Person Field (or whatever you would like).


    2. When = and(equals(Department,"IT"),isNullOrEmpty(Employee))



      • Department is the choice field.


      • Employee is the person field.






    3. Then = Invalidate


    4. Validation Message = Please enter an Employee (or whatever you would like).








Let me know if you would like me to provide this configuration for a Classic form.
