Edit: Please ignore this post. The real solution is in the following post.

Take each group individually:
Group 1: B+C+D=13
(1a) 9+3+1
(1b) 8+3+2
(1c) 7+5+1
(1d) 6+5+2

Group 2: D+E+F+G=17
(2a) 9+5+2+1
(2b) 8+6+2+1
(2c) 8+5+3+1
(2d) 7+6+3+1
(2e) 7+5+3+2

Group 3: G+H+I=17
(3a) 9+7+1
(3b) 9+6+2
(3c) 9+5+3
(3d) 8+7+2
(3e) 8+6+3

Find a solution from group 2 with exactly one overlap on a solution from each of groups 1 and 3 where there is no overlap between the solutions taken from groups 1 and 3.
