the "School form" in common application

<p>On the school form, I fill in some of my information, but didn't finish because I don't know my counsellor's name, I wanna add it now, but I coundn't click the "school form" anymore, can I change the information there?</p>

<p>P.S : even if I click the "school form", it appeared the different thing, it was asking me to agree something.... can I change that page that I had wrote something on?</p>
