Power Query Vlookup Dynamic Column Reference

Occasional Visitor

I have a query where Column "INDEX" values are the header names of other columns. I want to return the matching value. How can i do this in Power Query? Its basically a Vlookup with a dynamic col_index_num. I cannot seem to find a solution.. Thank you for the help!

In query on second table select KEY column, Unpivot other columns and add column with combined index. In query on first table create same combined index (KEY & "any text/symbol which is definitely not in your names" & INDEX), merge on it with second table and expand values only.
