Could someone help me with the syntax error here?

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

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value?("Bread") then grocery_item["food"] = "true" end

The answer is in the previous video "Working with hash keys" You need to use the .store() method to add the values to your hash. Not going to lie, I completely forgot this and had to redo the challenge to figure it out.

Hopefully that helps.

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

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