Could Someone Please Give Me a Hand With This Error: " Uncaught TypeError: undefined is not a function"

Hey guys,

So I'm building a form that features the form/email validation that Andrew Chalkley built in a early Treehouse video for the "Smells Like Bakin'" project. I've been able to implement it fine with other projects but for the site I'm currently building I keep getting the error: " Uncaught TypeError: undefined is not a function"

Here's the code block that seems to be throwing this error:

$("#email").validEmail({on:"keyup", success:function(){
    console.log('Code now works!');
}, failure:function() {

Any advice on how I can get this working would be greatly appreciated!


Stu :)

I do not believe that validEmail() is a method of jQuery's, so, unless you have created a jQuery plugin for it, it is not going to work. Alternatively, the problem could be that you forgot to add jQuery to the page or have a typo in the script tag, but I am thinking my first suggestion is your problem.
