Your task 1 code is fine.

The error message is a bit misleading. If you introduce a syntax error (like trying to call a variable as a function), it invalidates the entire script. And since task 1 is retested first, you get that message.

Anyway, if you remove that last line, your code is essentially correct, but the challenge is looking for a solution that expands the statement in task 1 to do everything in a single line. Try concatenating your additional elements in the original initialization instead of appending them on a separate line.

You might consider the challenge's picky expectations to be a bug. If so, you may want to submit a bug report using the instructions on the Support page.
