I'im using an index - match - match formula with links to an external file.

Everything works fine until I close the source workbook. At that moment the liks break. The error I'm getting is #REF!.

I suspect the reason is that the source data are in form of an official table. I tried some formulas with data in the same workbook but outside the table and they keep working after the source file is closed.

I really want to keep the source data in a form of an official excel table.

Any ideas how could I make it work?
