I am assuming you get these errors because the range is empty, you can use

=IF(COUNTBLANK(H3:H6)=ROWS(H3:H6),0,AVERAGE(IF(H3: H6<0,H3:H6)))

entered with ctrl + shift & enter

Here is my array formula. I would like it to return a ZERO instead of
#DIV/0. Have spent way too much time trying to make it work and thought some
kind soul out there would be willing to help me:

{=AVERAGE(IF(H3:H6<0, H3:H6,""))}

Thanks in advance!
