Can someone help with this?

Write an if statement that checks whether there are any skills in the bio object. If the if statement evaluates to true, . append() HTMLskillsStart to the div with id=header. Then .append() the skills to the element with id=skills using HTMLskills to format each skill.

Here is the object if that helps: var bio = { "bio": [{ "name": "Gary", "role": "Web Developer", "contact": [{ "mobile": 5555555555, "email": "garyterellchristie@gmail.com", "github": "GChristie1" "location": "Orlando, FL", "facebook": "GaryTerellChristie" }], "picture": "..images/fry.jpg", "welcomeMessage": "Hey there", "skills": ["Web Developer", "License Insurance Agent", "Fast Typer", "Bishop"] }] };

A link to the course video or challenge would be helpful. Unless the link points to Udacity. :stuck_out_tongue:

This can't be complete since I don't have the API for HTMLskills. But I can give you a few hints:

This object is deeply nested and contains arrays. Just to count them, you'd need a loop, something like this:

var total = 0
for (n in bio.bio)
  total += bio.bio[n].skills.length;

Then you could test total.

Then to select "div with id=header" you'd use $("div.header") (you're using JQuery, right)? And "the element with id=skills" is just $("#skills").

I hope that'll get you going.
