If I understand correctly, you have a Scrollview with a certain number of Panels and each Panel contains one EditText view and two Labels.
How did you set the Tag properties of the different views ?
If you have set the EditText Tag property to the line Index, then you can get the Panel view of this line with pnl = ScrollView1.Panel.GetView(Index).
Then you can get the Total Label with lblTotal = pnl.GetView(2).
It would be easier if you posted your project as a zip file, so we could see what you have done and how and update it.
Best regards.
