Conditional Formatting and Smileys!

Hi

Can you someone help me solve this problem. I have a list of numbers in one column and the column to the right contains a smiley I generate using wingdings.

I need formula that will

1) If value is less than 10 it will show a sad face with red background.
2) If value is greater than 10 it will show straight smile and orange background
3) If value greater than 20 it will be happy face with green background.

I can get the green and red but the orange is confusing me. I am using straightforward if function but I want to be able to use excels way of display greater than but less than.

Thanks forum!
