I'm wondering how you determine "doing what it's supposed to"? Be very careful about testing in an external REPL or sandbox tool. If you have misunderstood the challenge, it's also very likely that you will misinterpret the results.

In this case, the instructions said, "Assign this to the variable subject (so start with subject =)." So you know the last line must start with the word "subject" followed by an equal sign. And the format method can be applied directly to the template string, you don't need a variable for it. Keep in mind that the "format" method does not change the string you apply it to but returns a new string after processing instead.

And finally, you wrote "Treehose" instead of "Treehouse". The challenges are very picky about literal strings.
