Hi Darrel,

Thanks for the prompt reply and detailed explanation.
Please do not feel crushed. My comments were from complete despair and were not directed at you. I should have known better than to question your reply but I read that someone had managed to achieve what I wanted to do and I saw a glimmer of hope on the horizon.

Time for a re-think on how to achieve my desired result. Thankfully, I do like a good challenge

Cheers
Barry
