Yippeeee, thanks so much Kobra, I understand now.

Phewwww I was mighty slowww to pick it up though. I am learning new things every day, and thanks to your patience and excellent explanations I have been even more determined, as quite a few times I have just wanted to give up, as I really couldnt get my head around it.

I am sure a complete newbie like myself will come along one day, and this thread will be extremely helpful.

I really appreciate the time you have taken out to explain this to me, I would have never ever understood it if it wasnt for you.

Take care
Kind Regards
Nikki
