Hi,

I personally don't have the INDIRECT.EXT Add-In installed on my machine, though, assuming it does not differ in syntax from the standard worksheet function INDIRECT, I can see nothing at all wrong with your formula.

I can only suggest you re-check your cell entries in D4 and E4 and make sure they are correct, e.g. is the entry in D4 the full filepath? Is the extension still .xlsx, and not perhaps been (re-saved) as an .xls?

Regards
