Rhys, thank you for the suggestion of terminating with another SPACE. I recall that from somewhere in my distant past.
Alas it did not work and my totalisers are now flatlining again.
I have tried mixed case but am currently retrying with upper case only i.e. "NOCLAMPZERO ONEATSTART "
regards,
miles
EDIT: Yes i'm using the SMT 2.1.3 within Excel2007.
