This is a sample code for passing variable through form to report in axapta

 public void sumss()  
 {  
 str ss;  
 int tmp;  
 ;  
 //Element.selectMode(Element.control(Control::Sunny_CustMaster_NO));;  
 for (Table1 = Table1_ds.getFirst(true) ? Table1_ds.getFirst(true) : Table1_ds.cursor(); Table1; Table1 = Table1_ds.getnext())  
 {  
 tmp = Table1.SrNo;  
 }  
 iss = num2str(tmp,2,2,4,2);  
 }  
 call on clicked event of button  
 Args args = new Args();  
 ;  
 for (Table1_obj1 = Table1_ds.getFirst(true) ? Table1_ds.getFirst(true) : Table1;  
 Table1_obj1;  
 Table1_obj1 = Table1_ds.getNext())  
 {  
 args.record(Table1_obj1);  
 element.sumss();  
 args.parm(iss);  
 new MenuFunction(menuitemoutputstr(Traveling_Voucher), MenuItemType::Output).run(args);  
 }  
 super();  
 Pass to report like this  
 super();  
 //psum = element.args().record();  
 // sumss = element.args().parm("acc");  
 iss = element.args().parm();  
 element.SumRes(iss);  
 Table12 = element.args().record();  
 FetchNo = Table12.SrNo;
