Conditional Formatting for 1st column based on a positive or negative value in 2nd column

Hi there,

I have a list of keywords in one column and their changes in rankings in another - positive value for increase in rank (1) and negative value for loss in rank (-1).

I would like a formula which will highlight the keyword in either green for an increase or red for a loss.

There is most likely a simple solution but I'm relatively new to formula building within CF.

Any help is appreciated!

Thanks,

Andrew
