Error message say near a line that doesn't exist

It says near line 71 but I only wrote 17 lines of code

Can you provide more details, like what was the exact code you ran, which world were you using, etc.?

Some worlds, especially those that are not part of the standard tutorial, have extra code that is run before the user code (and is simply added to the user code) which can make the line number incorrect.
