I thought he was already using nested loops?  The outer looped through
the nodes selected by the key, then the inner iterated through all nodes
selected by the key using the FilingType of the context node in the
outer loop.  Since he wished to display AgencyName once in the inner
loop, using position() should be appropriate there.  I could have
misread the original post, of course.

Cheers,
