127?!? Agreed. Too convoluted. I need to learn how to use the Index and Match functions. It appears much more straightforward... but I will have to do some studying. Right now I only know that it works, not how.

from the beginning on:
The formula for INDEX is
=INDEX(range, row, column)
So you only have one column column is not needed.
You have to find the row of your range. Therefore I converted your
boolean values with the double minus to numeric values.
--TRUE=1
--FALSE=0
Then I combined both cells with the ampersand
--TRUE&--TRUE="11"
--FALSE&--TRUE="01"
and so on.
Using the ampersand the result becomes text. That is why it is in quotes
into the array.
=MATCH(---ER18&--ET18,{"11","01","10","00"},0)
looks for your combination of your cells
If you have in ER18 TRUE and in ET18 FALSE you get "10".
MATCH finds this value in third place of the array.
So your expected output is the third row of your range which is ER24.
