Good catch, Jan.

Actually, it could go a little further, if the bg that has the field is:
  in the stack but not placed on the current card
   in the stack and not placed on any card
   in the stack and contains a group
   in the stack, on a card, and has more than one group with the same field
name/number

Multiple fields on a card with the same name can happen.
One authoring short cut/valid technique is to group a set of fields and
controls so that group-copy-paste will produce multiples that are
self-contained using a group script.  Now the same controls & fields have
the same name, but not the same object id and object hierarchy.  This is
where using "the long name of me" should eliminate ambiguity.

try
get the long name of field "dataEyeWant"
--> error if no field exists
  answer "Rev found a field"
  if ("card id " & the short id of this card) is in it then
    answer "looks like the field is on this card"
  else
    answer "looks like the field is NOT on this card"
  end if
catch errrr
    answer "Rev could not find the field"
end try

I think Eric Chatonet addresses this in some of his tutorial stacks.
