I got a really confusing invoice in the mail today...

<p>I don't understand if I owe UMD money or what? I applied RD in Jan, pretty sure I paid my application fee, here's what the invoice says:
Term_<strong><em>Posting</em></strong>___<strong><em>Description of Item</em></strong><strong><em>Charges</em></strong><strong><em>Credit
2010</em></strong><em>01/28/10</em><strong><em>Prior balance undergrad application</em></strong>____________55.00</p>

<p>Billing Date: 02/25/10___<strong><em>Payment Due Date: 03/20/10</em></strong>_Total Amount Due: $-55.00</p>

<p>Messages: our records indicate you are not registered for classes for the Spring 2010 semester. Your bill must be paid in full before you can register for next semester. </p>

<p>I'm just incredibly financially challenged - what does this thing mean? I need to pay UMD $55 or they need to pay me $55? Why would they need to pay me $55?
And I don't know what that message is about, I'm not going to UMD for the Spring 2010 semester. I'm applying as a freshman for Fall 2010. So they would have to mean I'm not registered for high school classes Spring 2010? I mean I am, but I didn't send them a mid-year report, because they didn't ask for one. I put my classes on the application and everything though. I don't know. I'm confused. Can anyone help me out here?</p>

<p>EDIT:// Oh poo, as usual, I figured it out right after I posted my question. I think they're returning my application fee because I'm a National Merit finalist. Which brings up a new question, how do I get my $55? I paid by credit card, will they just credit my account, or do I have to do something?</p>

<p>They’ll credit your account.</p>

<p>Awesome, thanks!</p>
