Using ga with integer constraints: Constraints not close to being met.

Hello, I am trying to run a fairly simple optimization problem.
The objective is to minimize cost. The program yields results, but does not get close at all to meeting one simple equality constraint. I know that equality constraints can't be used with IntCon, so I have implemented the constraint with two inequality constraints (less than or equal to and more than or equal to).
I have attached the code. The main thing I'm looking at is the vector "Diff" which shows the difference between each element in what would be the b_eq constraint and the sum of the corresponding A_eq element. I would prefer each element in the "Diff" vector to be zero or VERY close to zero. However, in some places the value is as high as +/- 30. This is unacceptable for me.
Is there anything I can do so that the constraint is met much better?
Thanks in advance!
