Hi
I want to ask user to enter date then excel will return the average of temp1 and temp2 (reverse look up + array). My formula is this

=AVERAGE(INDEX(A2:C7,MATCH(F1,C2:C7,0),{1,2}))

(ctr+shift+enter)

but for the date 4/22/16 , excel returned 35 ! I was expecting (35+33)/2 instead. So excel is returning the first value only! Any idea why. Thank you so much.

By putting 0 in the column augment of index you tell it to return all columns, you also do not want to include the date in the array.
