I can't quite understand what is being asked. Every time I add a line to this code it claims that task 1 no longer runs.

Need a starting point.

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
grocery_item.has_value?("Bread")

if true then grocery_item.store("food", true)


else
end

Tyler,

You just have to combine your conditional check with the creation of the food item in the hash, give this a shot.

if grocery_item.has_value?("Bread")
  grocery_item.store("food", true)
end

You can also write that using:

if grocery_item.has_value?("Bread")
  grocery_item["food"] = true
end

Ruby is even simpler than they let on, thanks.

What I was more confused with was where to start for the value_at method that is asked in the next question. Sorry for not clarifying. Where am I putting the value_at method and what is being asked that I do?

Original question: Using the values_at method, create an array called grocery_list with the value of the grocery_item hash at the "item" key.

No problem Tyler, you'd just add that at the bottom after the conditional, so you're full code would look something like this:

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

if grocery_item.has_value?("Bread")
  grocery_item["food"] = true
end

grocery_list = grocery_item.values_at("item")

Gotcha, just the wording of the question that threw me off. Thank you for your help.

Could you post the code you're running just to make sure? I copied and pasted the last response from Tim Knight and it ran fine.
