The Preview button can be helpful, and for this code it prints out "James" (and nothing else).

The printf method is expecting a template as a first argument, which can contain substitution tokens for places to fill in using additional arguments.

If you need a refresher you can take a look at this portion of the previous video.

A "template" is the same thing as a "format string". The substitution tokens are codes like "%s" to represent where you'ld like a string to be plugged in. There are other codes for other kinds of values. The video calls these "format specifiers".

If you've resolved your original issue, you can mark a question solved by choosing a "best answer".
And happy coding!

Thanks a lot! What is a template? What are sub tokens?
