I have the following query which works fine except if there is not a value in D that matches F2. I get #N/A but not sure how to correct it so it shows "0".
ABS(QUERY(Transactions,"SELECT SUM(E) WHERE D = '"&$F2&"' AND B > date '"&TEXT($C$1,"yyyy-mm-dd")&"' AND B <= date '"&TEXT($C$2,"yyyy-mm-dd")&"' GROUP BY D LABEL SUM(E) '' ",0))
