creating monthly totals of meals served (voluntary org)

Hi

Im trying to create a tracking sheet for our volunteer org which feeds homeless people.

We input how many people we feed each day (B10 onwards) I would like to automatically add up feeds for the month starting from G4.

Looked online and have been battling with creating a SUMIFS formula for it but it is just not working, any help would be HUGELY appreciated

=SUMIFS($B$10:$B$100,$A$10:$A$100,”>=”&$F4,$A$10:$A$100,”<=”&EOMONTH($F4,0))

Thanks SOO MUCH in advance

SOLUTION: I was using the wrong type of " " Marks for it.
