How do I set a cell back-gound color based on it's value?

Before loading my grid I would like to set individual cell background colors based on the value that is in that cell for instance:
good = green
fair = orange
bad = red

I've found several example in the forum but nothing seems to work. I also have my grid with editable fields so once a user changes the value the cell background color needs to be updated.

Any thoughts?

Thanks in advance

I also forgot to mention that my grid is created from a csv file...if that impacts it at all.

Thanks again,

I did some more searching in the forum and found a solution that works!

Thanks for a great product!
