Hi Andrew,
Thanks very much for this, going to give it a try - I'll let you know.
Think that difference between n-dash and hyphen is what I was missing, although don't see where you've specified the type of dash (no Asc values).
To complete this code also need to include 1 - 3 digit numbers.
I'm dealing with 1 problem at a time, the current index has for example 129-1 - not ideal but understandable
