Regards,
I am typing an invoice in Excel, I have these issues:

1. The first column is nothing but a 'No.' column which increases one unit
each record, I guess there is a way to set this column cells to just be
their above cell + 1, isn't it? I can do it for one cell but I can't set all
cells of the column to use such formula at once.

2. I have an 'Area' column which is result of multiplying length column and
width column, again it is possible to do for one record easily but I wana
set this formula for all records of my sheet

I will be really thankful is someone help me soon
best wishes
