Hello Charles,
Thank you for your reply and the offer.
With the greatest respect, and I really mean that, I am not able to do a screenshot for you. The subject matter is a little private and contains names, dates and details that are not for public release.
I think I am near to a solution, if I continue what I am doing and if it is successful, I shall outline what I did and post it here!
I would like to think that it will save some other poor person hours of trial and failures!
I hope this is completed sometime tomorrow, I must 'cease and desist' for now, my "brain hurts"!

Regards,

Colin.
