I need help fnishing this sequence model (Solved)

Hi guys I need to do this sequence model but I am stuck on the finishing section. I just cant figure out how to lay this out right.
I attached a copy of what I have done. Here is what I still need to do :

a) actor commands system to register identified student (aStudent) for selected class

b) verify registration rules
if verified
student is registered
confirm registration
else
display error

c) system will allow student to restart at event 2 to register for another class

Any help or guidance will be so much appreciated.

I figured this out but thanks anyways.
