akapowl thanks ever so much for the in-depth explanation and my apologies for the delayed response. Really generous of you to go into so much detail as well as demonstrate an example which will help me understand the process a lot better.
Moving forward though I will most definitely bring some work to show before hand.....my apologies for that this time, I didn't realise.
Generally though I'm very impressed with the forum and look forward to learning more with you guys moving forward.
Thanks ever so much again.
