Hide and show on click

Hello!

In the project "Build an Interactive Website" --> "Introduction to jQuery" --> "Including jQuery in our Project" we add to the section of Cupcakes & Prices (of the Smells Like Bakin website) the ability to show the order form when the user clicks the order button with this code:

$(".order_form").hide();

$(".order_now").click(function() {

var $link = $(this);

$link.next().show("slow");

return false;

})

In my own project, the link doesn't disappear (in this case, the .order_now) unlike the Smells Like Bakin project.

My question is, how would the code be if I want that when the user click again in that link, the order form disappear again?

Thanks! :)
