How to hide related fields on details screen

[dan_R]

I’m working on “Store Details”, “Stores” view on my app. As you can see, all of the Ref fields are populating, even though there is no data in them. I would like them to show up if they are filled, but would like them to not show up if the field is empty. I have tried =ISNOTBLANK and I get an error.
Can someone with more brains than me PLEASE help?
