i trying send data 1 activity next activity when goes next activity displaying toast , no data

  tv=(textview)findviewbyid(r.id.textview1);     result=(textview)findviewbyid(r.id.result);      bundle data=getintent().getextras();     string marks=data.getstring("totalmarks");      result.settext(marks);

and retrieve :
