Gah I made a mistake!!! What do I do now?

<p>I submitted my resume in my additional info section but I just realized that I accidentally put two different #of hours for an activity</p>

<p>I accidentally put 12 instead of 20 for a certain community service activity (I did 12 hours for the activity right below it but never changed it)in the Activities section but I put 20 on my resume--what do I do?! I don't want them to think I'm lying!</p>

<p>...Anyone?!</p>

<p>Should I call the schools and tell them the mistake? Or will doing that make them think I'm a total idiot?</p>

<p>Help!!!</p>
