the best way is: put all your objects into flowing subfom (or put object into static subform afterwards put your static subforms into flowing ) and on checking or unchecking your checkbox event change the presence of your subfom;
formcalc $.presence = "hidden"
java this.presence = "hidden";
it is good habbit putting all your object into flowing flowing subforms. the structure of your forms should be: one main flowing subforms which consists of two flowing subforms one wich you want to hide and another which should be printed.
