Your help will be appreciated. PROBLEM: The formula below returns an answer
of 100% (WHICH ISN'T RIGHT). The correct result should be 11%.

=IF(COUNTIF(F18:M18,"<0"),LOOKUP(2,1/(F18:M18<0)*ISNUMBER(F18:M18)),AVERAGE(F18:M18)-AVERAGE(F22:M22))

WHAT I AM TRYING TO ACCOMPLISH (LAYOUT BELOW):
1) LOOKUP CALCULATED VALUES IN F18:M18
I.E. F18:I18
2) LOOKUP CALCULATED VALUES IN F22:M22
I.E. F22:I22
3) SUBTRACT INCREMENTING AVERAGE OF F22:M22 FROM
INCREMENTING AVERAGE OF F18:M18
