In a dilemma

I’m making a form that needs to add and subtract lines this is in (cs3, as2) I’m using visible or attachMovie actions to portray this. Anyway my problem is i need to only send the visible line into the form. I don’t want to send things not visible, and i dont want people to loose information from the other lines if they delete a line (i was thinking of putting different sets of forms for each line into different frames). Is there a way i can make this form the way i need it?
