The code looks good until the last line, it has a few issues:

  • the assignment operator is "=" (instead of ":")
  • the entire string should be enclosed in quotes
  • there should not be any numbers used, just variable names
  • the interpolation tokens inside the string are like this :point_right: \(variable_name)

You might want to revisit the Strings video where interpolation is introduced.
