Hi Mike,

The following works for me (I have changed the name of the counter to match yours) :-

oCounter = m.goapp.oregistry.lockcounter('%Shared.Counters.Primary Key Bcstypes')
if not isnull(oCounter)
  m.goapp.oregistry.setcounter(m.ocounter, '0')  && If key is integer type, you can send through a digit, no problem.
  m.goapp.oregistry.updatecounter(m.ocounter)
  m.goapp.oregistry.unlockcounter(m.ocounter)
endif
