Index with multiple match criteria (3 and more)

Hi y'all!

Here is what I have:

I have 20 cities.

For cities, I calculated labor costs, acquisition costs, rent expenses, and many more. They are calculated in a single sheet called Inputs.

Here is how it is organized:

Section 1:
Header: Labor costs (A1)
List of 20 cities: Paris to Marseille (B3 to B22)

Section 2:
Header: Acquisitions costs (A25)
List of 20 cities: Paris to Marseille (B27 to B46)

Section 3:
etc. for rent expenses and other sections

In the columns, I have dates (2021/2022/2023/2024) or monthly (2021-2024)

-------------------------------------------------------------------------------------

What I want to tell excel is that :

Go to the previously mentioned 'Input' sheet and Match "labor costs", then once you've located it, move to the below range and match the city, then Match date in cols and return the value

So I can get my results in the 'Output' sheet in the following manner :

Header: Paris (A1)

List of variables: Labor costs, Acquisition costs, Rent expenses, etc. (B3:B7)

Dates in columns (C2:F2)

And my matched numbers C3:F7


Attached, is a mock template articulating the question.


Many thanks !

Outputs

C6=IFERROR(IF($B6<>"",SUMIFS(INDEX(Inputs!$D$8:$CJ$275,,MATCH(Outputs!C$5,Inputs!$D$34:$J$34,0)),Inputs!$C$8:$C$275,Outputs!$B$3,Inputs!$A$8:$A$275,Outputs!$B6),""),"")

Copy across and down


C15=IFERROR(IF($B15<>"",SUMIFS(INDEX(Inputs!$D$8:$CJ$275,,MATCH(Outputs!C$14,Inputs!$D$7:$CI$7,0)),Inputs!$C$8:$C$275,Outputs!$B$3,Inputs!$A$8:$A$275,Outputs!$B15),""),"")

Copy across and down


I changed the file structure

The cities are selectable from the drop down list in B3

Thanks to all of you. I implemented the first one, gonna try the two others for the learning.

Many thanks for your time
