Hi Jacob,

The problem lies in the way you pass the argument to the @line_items_path@. You should only use the => notation when you are dealing with hashes. The call to @button_to@ should look like this: @<%= button_to ‘Add to cart’, line_items_path(product_id: product) %>@

You can also go with the old format: <%= button_to ‘Add to Cart’, line_items_path(:product_id => product) %>
