Treehouse TeacherThe full challenge text is:
Using the has_key? method, check if the hash variable has a key called "calories". If it does, set a new variable called "food" to true.
The code you posted is trying to set a key named "food" within the hash. The challenge actually wants you to set a completely separate variable named food.

Treehouse TeacherJeff Delacruz , in the line:
"food" = true
...it's attempting to assign a new value to the string "food", which is not valid code. If you remove the quotes, you'll be assigning to a variable named food, which is what you want.

Treehouse TeacherDharma Teja , sorry I didn't see your question before; hopefully you've already gotten an answer. But in case anyone has a similar question...
The task is to "set a variable", which in Ruby means that you just want this code:
food = true
There's no need to set a value for a hash key or anything like that.
