The .format() method in your code is taking the wrong argument.Change it your name variable

name = 'dom'
subject = 'Treehouse loves {} '.format(dom) # <-- here

dom is the value ⇒ you should add " ".

If you don't want to use " " (the value), you should directly use the variable name, name

Below 2 codes are the same, make sure you understand the difference between value & variable!!

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

subject = 'Treehouse loves {} '.format('dom')

Hope it helps!!!! Good luck!!

Does the variable dom exist?

Simple answer: No.

Since you didn't put double/single quotes around the text, Python will look for a variable called dom, which, of course doesn't exist.

However, even if you put double quotes around it, the challenge won't expect it. This is because the challenge asked ot you format the name variable, which has you name assigned to it.

Look here:

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

I hope this helps :smile:
