When ever you are trying to select elements on the DOM with jquery, selectors are passed in to the jQuery function as a string. Inside the string can be any valid CSS3 selector.

$(input,email).addClass.("valid");

look at what you are selecting. According to that, you are calling the jQuery function passing in the variables input and email.

I'm not sure I understand how to set up the correct foundation for these JQuery calls.... I wish there was more description for this question. Can you help frame the question a little better?

O.K. should it look more like $(#email).addClass(“valid”);

That's weird, works for me. Try refreshing and trying again.

That code works just fine. Did you put it in the tab labeled app.js?
