i may be trying to do something impossible here and hope to be wrong!
i`ve got two schedules for area calculation: a room schedule and an area schedule. The room schedule contains the room areas, the area schedule contains the gross floor area GFA. In order to find the structure building area, i would like to calculate GFA “minus” net building area (which means information from the area schedule “minus” information from the room schedule). What i acually want to do is find a way of integrating the information from the area schedule in the room schedule so that I can apply a formula for the calculation. Is there any chance it would be possible? This time i dont even know how to begin!
