I have changed my mind! In my previous email I happily accepted 14 was a problem. This was because I was seeing it as 'viv' in roman numerals because DBT changed 'xi' to 'viv' on the list in the attached file. (It is a WORD generated list which I know was not a good idea but it was a quick test!) I must think more clearly in future. However, is there a reason for this strange occurrence? David Spybey
