Cannot display content in Line Chart (Using Index & Match)

I am using below formula to get the values to populate a Line chart, but I am not able to see the values on preview screen:

=INDEX($D$6:$D$18,MATCH($D$22&$F11,INDEX($C$6:$C$18&$B$6:$B$18,0),0),MATCH($D$25,$D$5:$D$5,0))

Line chart is mapped to the cells: H11 to H23 in the excel sheet.

Attached is an image of the excel, I don't have and option to upload the excel file.

Any help will be greatly appreciated. Thanks in advance.
