I'm trying to make a calculation for a field, Head of Household Work Phone. I want it be that If it is empty, as in there is no work phone, then it will display the message "None". I'm close, but can't quite get it right.

But also, I want it more complex. I have a Spouse Work Phone field as well. I want that to do the same. However, some obviously do not have a spouse. So I would like to make that conditional upon the Spouse First Name field being filled. Because obviously if it is empty, there is no spouse and I don't need the message "None" in work phone

Thanks for your help finishing these off.

Head of Household Work Phone:

Case( 

      IsEmpty( workphone ) ; "None" ; 

      workphone )

Spouse Work Phone:

Case( 

     IsEmpty( spouse first name ) ; "" ;

     IsEmpty( spouse workphone ) ; "None" ; 

     spouse workphone )
