Hey Steve,
You really do give it 110% when you respond here.
Just today my energy column was of bright white lights, a bit like when Captain Kirk et al where being beamed down to the nearest planet!
I think I must be getting somewhere with all this - can't wait for level 2 :-)
As with your other contributions I will need to read it again and consider carefully the advice you have so generously given.
Many thanks for your time, trouble and expertise.
Cheers till next week.
