I have 15 sheets that use the same template, for 15 different users. I would like to make a query on all the sheets, and display the result in a separate sheet:
=QUERY(Mona!A3:U300; "select A, D where C != ''")
Where Mona
is the name of 1 of the 15 sheets.
So what I need is to make this QUERY on all the sheets and show the result. The columns (A,D) should only occur once.
How can I accomplish this?
