Equation Grab and Insert into Ratio

Insert data from yahoo finance. Look at Row name and grab data from column and fit into ratio.

For example: Find "Net Income" and divide by "Total Revenue" from Year 2012 (or column).

The idea is to grab and insert data efficiently without having to search for names individually. I can set up the ratios myself if I know how to grab information effectively. My best guess is to somehow use an array.
