Hi Julie - I believe that the compiler has made a mistake in the top right hand corner. Line 2 should have 2 x 1s after the three. and line 3 should have 7 x 1s after the three and that is how I am submitting mine. My grid actually has a small dot printed at the very right end of line 2 as if there was to be another digit. I'm surprised that no one else has spotted this - good luck J
Hi, I can also confirm the error and I think that the error has occurred because of the restricted space available on the right hand side - the longer the sequence of numbers obviously the more room is required if that makes sense. I agree with the solution offered by required rockfordill.
