That will work as long as you can guarantee only one element in the
Array. The fact that the method returns an array and not a single
value indicates to me that there may be times where multiple elements
are a real possibility. You may want to consider accessing the first
element explicitly with ErrFieldID[0] instead of using to_s.

You may also want to consider what to do if you get more than one
element returned in that array.
