klaus Expert Licensed User Longtime User Oct 12, 2014 #4 If you used the layout from the first program there is an EditText view called edtResult. This view should be replaced by a Label in the second program. I suppose that you didn't replace it in the Designer or you didn't change its name from edtResult to lblResult. Look at pages 40 and 41 in the Beginner's Guide. Upvote 0
