You know what, things got mixed up.
I was actually on the 4th task for 1.7.
I'm not sure what happened but it looks like tasks 1 - 3 / 4 got deleted and I need to redo those.
that's whats causing my confusing, I was trying to do task 4 on the first task.
I am a little confused as to what it's asking for task 4, though now that I figured out what was giong wrong.
Here's what I entered into the li for task 4:
<li><?php echo $population; ?></li>
I think it's just asking me to add it similar to country and established above, right?
Edit: My mistake, the issue was being caused by me not adding Population: to the list item.
moderator: No worries, and thanks for updating this to indicate you figured it out!
