How To Use Index Function When Have Multiple Matches

So here is how I have a template laid out:

A
B
C
D
E
F

ROW 1

Period 10
Period 11


[Code] ........

Cell E4: =SUMIF('P10-2011'!$A$4:$A$272,'Budget Upload'!$A19,'P10-2011'!$H$4:$H$272)

I have a SumIF statement in cell E4 but I would much prefer some sort of index or something where I can drag the formula down because the cells in column D will change (and require me to pick a different SUM range for my SUMIF function). Now my issue is I have multiple matches so when I use a typical index it returns the FIRST match.

Here is the formula I used in cell E11 to try and replicate the result in E5:
=INDEX('P10-2011'!$A$2:$Y$272,MATCH('Budget Upload'!$A4,'P10-2011'!$A$2:$A$272,0),MATCH('Budget Upload'!$D4,'P10-2011'!$A$2:$Y$2,0))

My index function works as it is designed but only returns the FIRST match. I should have multiple matches.

Is there a way to use an index function to return multiple results?

To clarify,the index function I put in cell F4 returns only ONE column (which is correct and will always be correct), which is related to the cell D4 but I have multiple rows (related to "7002" row match portion of the index function).
