Error message on supplement?

<p>I keep getting an error message when I try and save my supplemental application for St. Mary's! It keeps saying that there are invalid characters in my application, but there are none. This is also happening to my friend's application. I tried working on mine on two different computers but the result was always the same.</p>

<p>What's going on? Should I call commonapp or St. Mary's or what??</p>

<p>I would start with calling St. Mary's. Smaller group of people to talk to, and they are very nice. Is there a phone number for the common app? I had no idea you could actually talk to people :)</p>
