Answer 1

Looks like lblprvbal isn't an object. Meaning, you don't have a TextBox called lblprvbal in your form, even if you think you do. Maybe because its real name is lblPrvBal? That would be consistent with your other object names. As a side note, you probably don't want to start a TextBox with lbl, which suggests it's a label.

Answer 2

Try below. value in the sub item is null and hence the error.
If IsDBNull(NewItem.SubItems(11)) Then
lblprvbal.Text = ""
Else
lblprvbal.Text = Val(NewItem.SubItems(11))
End If

Answer 3

Check if not NewItem is Nothing.
