What is my error?

It says: ''There was an error with your code: TypeError: 'undefined' is not a function (evaluating 'this.prepend('<label> <input type="checkbox"/> </label>')')''.

Hey Julien,

Your code should be a jquery statement and begin with $. (this) should have curly braces around it. You have an extra label element in your code that is not needed. And finally add a semicolon at the end of your statement.

Thanks, but now that I corrected this it says: ''Within the anonymous function passed to the "each" method call, did you supply the argument "'<input type="checkbox"/>'" to the "prepend" method call on the jQuery object with an argument of "this"?''.
