Attacking the Serve

[ReadyToRef]

We are calling Middle School VB using Fed rules. The only difference is the net has been lowered two inches. We need help with deciding what is and what is not attacking the serve.

I say that if a serve is going to a front row person,then that person is allowed to play the ball back over as long as the ball is not above the net.

Am I wrong? I would greatly appreciate any and all clarification.
