A prompt dialog will open prompting for someone's full name. Use jQuery to follow the comments in code. First, select the correct input, and then set it's value to the fullName.

js/app.js 
//Show Prompt Window and store value
var fullName = prompt("What is your full name?");

//Select Input with the id of #fullName

//Insert value in to full name input

<!DOCTYPE html>

Hi

I'm guessing you are struggling to select the input and put the value of fullName into it so here is is with jQuery if you want to select an item on a page with an ID you would use

$('#fullName');

The # symbol is required for anything from a div to a paragraph tag that has an id you want to select.

the solution to your code would be 

//First Select the input with the id fullName then use .val() to plug in the value of the fullName variable
$('#fullName').val(fullName);

Further more if you are selecting a class instead of an ID then you would use . instead of # like so 

$('.fullName');

hope this helps you out.
