Hi all,
Would appreciate help with making this formula work:
=AVERAGEIFS([AVG range];[criteria 1 range - numbers];[criteria 1: all empty cells];[criteria 2 range - dates]; [dates before <22.01.2014 and after 04.01.2015])
right now written as =AVERAGEIFS($D$3:$CQ$3;$D$5:$CQ$5;"";$D$2:$CQ$2; "OR(<22.01.2014; >04.01.2015)")
but it does not work this way... must be some stupid mistake. Please, help!
Thanks much,
D
