    I have a solution I have triple checked that I don’t see anything wrong with, that the checker says is incorrect. I am wondering if there are 2 ways this one can be solved or if I am just missing something.

      As this was part of the Grand Prix competition, the solution is available here (but rotated). Without seeing your answer, I cannot comment on any issue with it but the puzzle has a unique solution.

        Thanks, that is the solution I got, now to figure out why how I was inputting it was wrong.

          It appears I misunderstood how to submit answers, I was putting in the widths of the unincluded space instead of the included space. Oops. Thanks a lot!

          Sorry that the answer key description was the cause of the problem but glad you got this sorted out. We do show answer examples for this and other puzzles on the rules page, but I see how not having it appear on the post can cause problems.
