  Amend the fares list to replace nulls.

  The solution shows ‘@[fares;where null fares;:;avg fares]’, but to actually amend the list, it should be @[`fares;where null fares;:;avg fares], right? The backtick is needed to amend the fares list.

  Yes you need the backtick to amend the fares list. Leaving it out just returns the modified list, which you could then assign to another variable

  I should have been more clear in my post. The solution in the exercise is wrong. It mentions amending the table, but their solution doesn’t include the backtick.

  Thanks,

  Hi Megan,

  In Session 3 Data Structures, Exercise 17 it says “Amend the fares list to replace the null values to be equal to the average value”. The solution it shows is “@[fares;where null fares;:;avg fares]”. This is incorrect. It’s missing the tick prior to “fares”.

  Thanks,

  -Richard

  Perfect, @Richard-Mandel thank you for bringing this to our attention. I will take a look and adjust this solution.

  Thanks again,

  Megan
