Formula To Calculate Turnaround

I am trying to calculate the number of items that took more than 5 days to complete.

The user enters the month and the year for which stats are required in G5 and G6, respectively (e.g., February and 2008). Both cells are formatted as General.

Column D contains the start dates, while column Q contains the completed dates.

I used the following formula but I am not getting the expected result:

PHP

=SUMPRODUCT(--(DATE(YEAR($D$10:$D$12),MONTH($D$10:$D$12),DAY($D$10:$D$12))>=DATE($G$6,CHOOSE(MATCH($G$5,{"January","February","March","April","May","June","July","August","September","October","November","December"},0),1,2,3,4,5,6,7,8,9,10,11,12),1)),--(DATE(YEAR($D$10:$D$12),MONTH($D$10:$D$12),DAY($D$10:$D$12))<=DATE($G$6,CHOOSE(MATCH($G$5,{"January","February","March","April","May","June","July","August","September","October","November","December"},0),1,2,3,4,5,6,7,8,9,10,11,12)+1,0)),--($D$10:$D$12<>""),--($Q$10:$Q$12<>""),--(DATE(YEAR($Q$10:$Q$12),MONTH($Q$10:$Q$12),DAY($Q$10:$Q$12))-DATE(YEAR($D$10:$D$12),MONTH($D$10:$D$12),DAY($D$10:$D$12))>5))
