Foul calls/enforcement

[abergman]

Hi, I'm a new official, I believe I have a grasp on these ideas but want to make sure by running some things by you guys.

When a foul is called away from the ball on a shooting play, i.e. foul undernieth while three point shot is being attempted. What is the enforcement on offense, defensive fouls? Count the basket? If someone could go through all the scenarios I would appreciate it.

Thanks
