Yeah, but I think this means that I will have to build some kind of a tool that will let the user design his reports and this means that a lot of time will be spent just for the creation of this tool... time that I don't think I have... I guess now all I can do is present all the methods that we could use for this situation and wait for the answer... whichever that will be. Thank you for your help anyway... it cleared out many questions 🙂
