I am trying to do an array multiplication, multiply each of the months with the corresponding numbers from the 'Array' below, for example for "Person 1" do 0.1*150, then 0.2*250 and so on.
As you can see it is returning #VALUE. Even if I try multiplying as an array, or multiply the numbers one by one it still shows #VALUE. What is the problem here and how to fix it?

The formula for the Array results: =INDEX($A$10:$L$10, MOD(XMATCH($B14, $A$9:$L$9, 0) - 1 + SEQUENCE(1, 36, 0), 12) + 1)
