Fee Waiver???

So I applied to WCU as a transfer student and clicked fee waiver (because in highschool I used one for the SATs…) Anyways I went on college board turns out I don’t have a fee waiver but I already sent the application, how do I pay for the college app, will the college not get my application unless I pay???
