How do I add auto text based on value in numeric field?

Need help... I'm trying to add auto text to a text field based on a value in a numeric field. I want my text field (summary box) to say "Passed" if the value (score box) is equal to 10 and the field to say "Not Passed" if the value is equal to less than 10. My numeric field is being calculated by selecting drop-down lists.

Thanks in advance for your help.
