jQuery .closest() works on one page, but not another

<p>When you click on the game background it'll open a Amazon.com link. For some reason on the forums it's failing and giving the error <strong>$(event.target).closest is not a function</strong>.</p>

<p>The second function is the one in question. The jQuery version is the same on both pages, so I can't figure out what the issue could possibly be.</p>
