Why is this Ruby block wrong...?

How is it that I'm getting an error stating the has_value? method has not been used...?

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

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

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

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

This is what i wrote to produce what you needed in your code. If you look i passed the "has_value" an argument of "Bread" in my first line....I didn't try to do a comparison operator. What happens is if the line that i put is right, it will return true anyway. The line after which is how i add to my hash. You do not need to reassign the whole grocery hash by doing "grocery_item =" .... what you need to do is add on to the pre existing hash already. There are multiple ways of doing this. Hopefully this helped.
