Thank you all. I do appreciate your replies. Funny thing is, I need to use this advice today, so your help could not have come at a better time. It was great. Many Many thanks. But I did get rather a "rush" while I was trying this... Lucky I went easy. Going to take some practice to get this working I think...

Sonya - You always know the right thing to say to me.

Det - Thanks for your story. Amazing what we can be done with energy.
