<p>Do you mean you informed UPitt that you will not be accepting their offer of admittance?</p>
<p>If so, call up UPitt and ask someone in the admissions dept. if your child can retract his/her decision not to enroll and change the decision to—yes, plan to enroll.</p>
<p>After speaking with UPitt and confirming that your child will attend, simply tell NYU that you have had a change of heart and have decided not to attend NYU.</p>
