Having some issues

I'm trying to create a variable called subject that includes the string "Treehouse loves {}", .format(), and my name variable, which I assigned as "Kiren". When I run the code, I am getting an error message that is saying that Task 1 is no longer running. I'm not sure what that means.

strings.py 
name = "Kiren"
subject = .format("Treehouse loves {name}")

You are very close. format() is a method of str. So the syntax is to add ".format()" at the end of the string:

name = "Kiren"
subject = "Treehouse loves {}".format(name)

In evaluating this post I tried using named format fields and it was rejected:

name = "Why Not"
# this is rejected
subject = "Treehouse loves {name}".format(name=name)
# so is this
subject = "Treehouse loves {0}".format(name)

The Checker appears to insist on an empty format field {}. Is this overly restrictive?

Yeah, I'd say that's too restrictive, Chris Freeman. I've updated the CC.

errors in current tasks can cause it to say there are now errors in previous tasks. here you are using format wrong. format is a method and you call it on an object like object.format(arguments). so here the string treehouse...is your object, call format on it, and then the argument to format is the name variable. string.format(variable). the {} in the string are empty, they are a placeholder. the format method will fill them in with the argument to format, name.
