Hello guys, is there any way to sum results from match index if there are several positive results from the formula itself?
My formula is following:

=INDEX('123YELP'!$1:$1048576;MATCH([@AA];'123YELP'!C:C;0);MATCH([@[BB]];'ABA.xlsx'!Table1[#Headers];0))

It does show me the first match which would be customer A matched with Q1 so value is 100 from below example but I need to sum all results from customer A and Q1 result.

Customer Q1 Q2
A 100 200
A 150 210
A 90 150
A 70 140
B 100 200
B 150 210
B 90 150
B 70 140

Best regards.
