Sorry if this is a duplicated question.I have several spreadsheets with plenty of source data,In which I usually use INDEX+MATCH to find out the source data for the corresponding value,As shown in the graph here, this is just an example.

Clik here to view.
Example sheet here:https://www.dropbox.com/s/yixftcr83tkoid2/example_sheet.xlsx?dl=0
Usually I need to see only some selected user's data on a specific month, it can be done by INDEX+MATCH(or vlookup), but now I want to add a sum for these selected user data on specific month. In the real sheet I have a lot of selected users and also lots of different month that I want to compare of, so I want to avoid doing the J10 SUM again and again. Is there any way I can do this?(Basically to a single task that finds the index value for user listed in I7-I9 and then sum up...)
P.S my actual list for index/match is more than 5,000 rows so I use like X:X for match.
