Summing up results from index, match

[afika]

Hi All, hope you are having a good day..

I have used Index and match function to pick up data from a data base. However what I need is to sum up and values of multiple mathers.

Below, in the left is the data base, in the right is the picked up values for 'GL1-Brand1-Jan'.
But in the data base for 'Jan & Brand1' there are two GL1 values, 300 and 200, so I need to get the look up value sumed up to have the result of 500. (Formula used --> =INDEX($D$3:$F$7,MATCH($I3,$C3:$C7,0),MATCH(J$1&J$2,$D$1:$F$1&$D$2:$F$2,0)). Pls help, tahnks

	Jan	Jan	Jan				Jan	Jan	Jan
	Brand1	Brand2	Brand3				Brand1	Brand2	Brand3
GL1	300	500	300			GL1	300	500	300
GL2	400	700	700
GL3	500	400	900
GL1	200	600	900
GL2	100	300	200

How about
=SUM(FILTER(FILTER($D$3:$F$7,$C$3:$C$7=$I3),($D$1:$F$1=J$1)*($D$2:$F$2=J$2)))
