Sumproduct over dynamic range

Hello Excel guru's,

Can the following formula be adapted to run over a dynamic range. Currently it will only work if the range is fixed to those rows containing data, just the first 21 rows.

=SUMPRODUCT(--('QO'!$J$12:J500="SQ"),--('QO'!$F$12:F500),--(MONTH('QO'!$E$12:E500)=MONTH(TODAY())))

I'm using Sumproduct because it will be pulling data from a closed workbook.

Thank you
