Using Cell As Array Reference In SUMIFS Formula?

I have a report for which I would like to set up a Quarterly summary section. There are 6 working teams listed in my table and I have created two cells with data validation to allow me to specify which team and for which quarter I would like to pull data. My intent is to have a formula in one cell which can extrapolate the quarterly team information based on the values in the data-validated cells.

My worksheet is set up so that:

The data table (tblD) contains metrics for all teams for the full yearTeam names appear in Column A of the table and the reporting month appears in Column BCell M10 has data validation so that the only choices are: Q1, Q2, Q3, or Q4Cells X1:X4 contain the quarterly values mentioned aboveCells Y1:Y4 contain array references, so that Cell X1 = Q1 and Cell Y1 = {"January", "February", "March"}Cell N10 contains a VLOOKUP which returns the appropriate array from Column Y based on value in Cell M10Cell L11 has data validation so that the only choices are the 6 team names

Now I was able to get quarterly information by manually typing the 3-month array into my formula like so:

Code:
=SUM(SUMIFS(tblD[TU5],tblD[Team],$L$11,tblD[Month],{"January","February","March"}))

BUT! When I try to use a formula which points to the VLOOKUP cell (N10)--thus allowing me to make the display dynamic--the result is always 0.

Code:
=SUM(SUMIFS(tblD[TU5],tblD[Team],$L$11,tblD[Month],$N$10))

While inspecting the formula in the formula bar, I noticed that the values listed in the array appeared with double quotes (i.e. "{""January"",""February"",""March""}"). I tried every permutation of typing the array in the lookup cells I could think of, but none would allow my formula to properly calculate the total I needed.

{"January", "February", "March"}
{January, February, March}
January, February, March

Although I don't often utilize arrays in my formulas, I do employ them from time to time. I'm hoping there's some factor I might have overlooked which keeps my formula from working. is there an issue preventing array references stored in cells from being used in formula?
