SW-View Scale property - which view does it choose scale from?

If you have multiple views on a drawing sheet, from which view does it pull this property? I've tried to use SW-View Scale to link to text in the titleblock, but the value comes up blank, even though I obviously have a scale in my drawing views.

Perhaps I'm missing something to get this to work...........any help would be greatly appreciated!
