how to vlookup based on one row and 2 columns?

Hello there
I found a index + match Google sheet formula to find a cell based on row AND column. But I was wondering if it's possible to do it with 2 conditions from the header.
I have 2 scenario represented in sheet 1 and sheet 2:
FIRST: find the cost share of a certain product for a specific market
SECOND: find the cost share of a certain product from a specific range and for a specific market
I would appreciate any help you could provide, please

Many thanks

find a cell from multiple values.xlsx

Sure thanks: I would like to automate the highlited cells because I have lots of tables like this for all different countries with lots of productsfind a cell from multiple values (1).xlsx

By the way, it's not a calculation. Its a vlookup of a cell but based on multiple criteria. Hope it's clearer

the expectation are not a calculation I just want to "call" numbers from sheet 1 into the yellow cells. But because I have many tables like this in my original sheet with many countries, it's a pain to do it manually and I would like to find a formula that is "finding" a cell based on 2 headers and 2 columns.
Hope it's clearer

Brilliant!!!! thank you so very much. It saves me lots of time :D
