Update: Well as you can see I got my old template back. My head hurts with trying to figure this thing out but thank you Squirrel Queen and thank you Betsy for the comforting words and good advice. I had to convert back to 'layout' as all the tinkering I did changed it to 'template'. I am so confused, I still don't know how I did all of this but thanks to the help forum at least I got back everything. I had not lost it all as I had first thought and that was making me feel awful.
I still can't comment on my own blog but I will do as Betsy suggested and contact blogger direct.
