I'm not sure what I'm doing wrong.

name = 'Matt Lewis' subject = 'Treehouse loves {}!' print(subject.format(name))

strings.py 
name = 'Matt Lewis'
subject = 'Treehouse loves {}'
print(subject.format(name))

Hey Matt,

You just have your .format on the wrong line. It should look like this:

name = 'Matt Lewis'
subject = 'Treehouse loves {}'.format(name)

print(subject)

When you try to add .format to the print line, it doesn't know what string you're trying to interpolate, since that interpolation (the {} characters) is located in the subject variable. You include .format there, and specify the variable containing the string you want to interpolate.

Hope that clarifies things! Cena
