Why Sum?

This puzzle was for palflys birthday. Learned just of y-sums and found them to be a fun indexing constraint. Feel free to give positive or constructive feedback, both are welcome I can learn more from constructive feedback

Rules:

1. Place the digits one through nine in every row column and 3x3 box.

2. Clues above and below the grid are y-sums. Where X is the closest digit to the clue, and places "Y" in the Xth posistion of its respective column. Y indicates that the first Y cells from the clue, will sum to the clue in its respective column. For example, a 10 clue could mean 3142, 372, 73 and 2 in the 7th position, etc.

3. Clues on the left and right side of the grid are numbered Rooms. Where N is the closest digit to the clue, and places the clue in the Nth posistion of its respective row.

4. A digit "P" in a cage points vertically or horizontally at a digit K. Where K is P spaces away. The value in the top left corner of the cage is the sum of P+K.
