As far as your second question is concerned, what did it tell you when you
typed namebox into Excel help?
For the first question, it might have been better if you'd given the full
details when you first asked the question.
Put 42.33 into A1, then in B1 put =A1+0.01 and copy across C1 to P1.
In A2 put =P1+0.01. Copy B11 down to B22. Copy A22 down as far as
necessary.
