UPenn Supplement

<p>So for the past five hours, I've been trying to submit my supplement. </p>

<p>I keep clicking "Submit" over and over again, but it hasn't let me. When I click "Submit," my browser shows signs of loading, but the page remains the same. </p>

<p>Anyone else having this problem? I tried submitting my supplement on both Firefox and Safari and it hasn't made a difference...</p>
