Thanks guys,
I didn't have a lap top as the new battery I had ordered had not arrived so I was doing it manual. I did actually forget that I could use live view and zoom in. I don't get much time to try this type of photography and by the time I get to try again, I've forgotten it as I don't write anything down.
Better luck next time. I'll look up how to use one of those calculators, too.
Cheers!
