Well, my question is, that while we have a "form" where we charge our campaigns, each campaigns maybe have more than one work in it, so we have a "subform" in it, where we can just press "add" buttton of the subform and add every work in it, in each work charged in this Subform, we select the Personal who work in it, we have a field "lookup" where we choose the personal. So what i need to do now, is bring a report where bring the information of all the work did for each personal so i can know how much we have to pay to every personal we have. 

        Will apreciate your help ! thanks a lot !
