I just tried something which worked and maybe revealed the bug.
I restarted the exercise, then went step by step.
Please keep in mind that:
- All my steps were checked green except for the last, for which I resorted to fetching the solution code.
I had already tried going step by step after having retrieved the solution code a few times (which never worked). I emulated the solution code closely, the only difference being that I inserted my own value for the "feet" integer.
I decided to use the exact integer that the solution code used (even though that should be irrelevant) (my integer was 100).
In the place where you enter the integer to denote "feet" i entered the number 40 just like in the solution code, written thusly:
Guess what! It worked. I can now move on to the next buggy lesson. :[ :[ :[
