Google Sheets: Sum up a vLookup formula within an ArrayFormula

Hi,

I am trying VLOOKUP with Multiple Criteria in Google Sheets Using ArrayFormula, since there are more than one value on the table.

I need to SUM UP all the numbers that matches the criteria.

Could you tell me where I can add "SUM" into the below formula? Truly appreciated it


=ArrayFormula(iferror(VLOOKUP($H$2&H3,{$B$3:$B&$D$3:$D,$E$3:$F},3,0),0))
