Prison Negativity

Rules:

Use six digits of the digits from 1-9 to fill the grid, with each digit appearing once in every row, column and box. Which six digits are used must be determined by the solver. There are six negator cells to be found, one in every row, column and box. A negator cell has negative value (eg: a 4 in a negator cell would have a value of -4.) Every negator cell contains a different digit. Digits do not repeat in a cage, and the values of cells within a cage must sum to the clue (if one is shown). Orthogonally connected digits in a cage are of different parities (one is odd and the other is even).
