I see two things that I think are throwing off the interpreter. First, it looks like you have a space after your curly braces, which means there will be extra whitespace at the end of your formatted string, so it won't precisely match what the challenge is asking for.

Second, since you're not printing anything, you need to call .format() directly on the string to format, rather than trying to call it on the variable. For example, if you were printing, you could do this:

name = kipre
subject = "Treehouse loves {}"
print(subject.format(name))
# output: "Treehouse loves kipre"

In this example, though, the value of subject will still be "Treehouse loves {}". For name to make it into the actual variable, you need to call .format() when setting the string. Let me know if you need further clarification!
