I have a set of records which have a 6 character reference. There maybe more
than one record with the same reference.

I already have a way of counting how many records there are with a
particular reference.

When I press the search button I want a counter that says 1 of N, when I
press the search button again I want the counter to say 2 of N (where N is
the the total number of records with a particular reference).

I hope this makes sense.
