Re: [O] sum up variables from different org-mode tables

[Martin Gross]

Dear Michael,

thank you very much, this is what I was looking for.  I myself
supposed the answer should be related to "remote references", but was
not sure how to use them.

Just one point is not yet optimum to me: I do not have just 2 tables,
but hundreds.  It would be hard and not very clean to add them all one
by one.  Do you know if it there is a better way to reference remote
tables?  For example telling org-mode to search data from all tables
but "this" one?

Best regards,

Martin
