There are a couple things wrong.
- Whenever you see the instructions for "do this if..." or "if this, then...", you are pretty safe to assume you'll need an if statement in your code.
if hash.has_key?("calories")
# do something
end
- If it does have the key calories, it wants you to create a new variable called food (just like hash in the first line) and set it to true. This should go inside the if block, right? IF it has the key, then create the variable.
food = #what should go here?
Right now you're adding puts, which is to literally print out a string, which is not what it's asking you to do. Tweak these things and you'll pass.
Good luck!

or if hash.key?("calories") food = true end
Still not compiling.

19,817 PointsThe challenge specifically wants you to use .has_key? method. Make sure to use
hash.has_key?
and not
hash.key?
The second way you did it is the correct way, just use the correct method and you will pass.
Have fun, Mike
