I can't see anything wrong with this:

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

if grocery_item.has_value?("Bread") grocery_item = { "food" => true } end

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



if grocery_item.has_value?("Bread")
  grocery_item = { "food" => true }
end

Not sure why you would write it like this, but this is the correct answer:

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

Sorry, I was not very specific yesterday. My version gets an error saying "the has_value? method was not called.". Maybe it's a bug in the system. Your version works.

Thanks, Frank.
