Fill in the grid below so that
(a) each of the digits 1 through 9 appears in every row and in every column, and
(b) the number given in each subsection (separated by double lines) is the sum of the numbers you've placed in that subsection.   I've filled in one subsection (4 + 8 = 12) to get you started.

Please send your answers as a 9 x 9 grid of just the 81 integers.
Do not include the sums in each subsection.
