Excel 2013 - conditional format with dates

Hi

I have a workbook that logs courses people have been on and I type in the date the qualification needs to be renewed. I would like that cell to change colour when it is so many days before the renewal date using the =today() function.

pale yellow - 60 days before renewal date

orange - 30 days before renewal date

red - expired, i.e. today's date is after the renewal date

I have an idea how to do it but I can't seem to get it working exactly the way I want it to.

Thanks.

Viv
