I'm having a hard time understanding how to accomplish what seems to be a simple result.

I need to display one of two words, based on whether or not a pair of values are above or below the criteria.

FIRST:
IF H6 is greater than 5000
AND
IF AB6 is greater than 25000
Display: Double

SECOND:
IF H6 is less than 5000
AND
IF AB6 is greater than 25000
Display: Single

There is no 3rd scenario, even though logically there should be.
