Hi Ross,
It's all working fine now, thanks very much!

You know, if I'd gone back to it now I'd have probably spotted this,
I've spent the intervening time fiddling with other diagrams and it's
all a bit more familiar now.

Sorry, I thought you were saying with \drop or \POS it coudl work at
the start *or* elsewhere -- not a problem though because all of those
one appear on their own (either in labels or cells).
Many thanks for getting me straightened out on this.
I do have a couple of other questions, not urgent though, they can
wait for another day in case I solve them first.
Cheers,
Andrew.
