Hi Alex,

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!

Mike

These were my two options: if hash.key?("calories") hash.store("food", true) end

or if hash.key?("calories") food = true end

Still not compiling.
