Dear Sailor Steve,
Thanks very much, it must have been the numbers not running sequentially. I removed the blocks numbered 'g3f i300' to 'g3f i307'. I then renumbered the blocks 'g3f i308' to 'g3f i336' to 'g3f i300' to 'g3f i328 (I think that last number is correct)'. I also made the change to the Dials file and gave the whole cabush a go

Yayyyy, it works a treat

Thanks very much for your kind patience and understanding on this Steve - I am indebted to you and I sincerely hope others may benefit from this thread.
Alles gute mein freund und gute jagd
