Color more than one cell on the same row when a cell has a certain numeric value

[dvp]

A B C D
1 Name 2009 2010 Total
2 Sam 400 600 1000
3 John 200 400 600
4 Eric 100 300 400


I'm working on a simple list, see example above, where a cells background color changes (in a simple traffic light system) in both the Total (column D) and Name (column A) when the cell value in D has certain numeric values, ie Green if total >=1000, Amber is between 500-999, Red<500. I've used a conditional formatting sequence using Ms Excel 2010 to highlight cells in D. However, how do i create a sequence or code so that the corresponding cell in A of the same row is colored the same way? For example, D2 is Green, and i want A2 to be Green as well? How do i do this?

Just specify the range in the Conditional Formatting Rules
