VBA IF SUM Function

I am trying to write vba code that completes this task on a range of cells with values: =IF(SUM(A2:B2)>0,"Yes","No")

but cannot get it to operate correctly. Here's what I have so far. Sorry I'm new to vba.

Sub formula3()

    'formula3

    On Error Resume Next
    On Error GoTo 123:

    Dim i As Long
    Dim lastrow As Integer
    Dim wsClient As Worksheet
    Set wsClient = ThisWorkbook.Sheets("All P&C Client Data")
    lastrow = wsClient.Cells.Find("*", wsClient.Range("F1"), xlFormulas, xlPart, xlByRows, xlPrevious, False).row

    For i = 2 To lastrow

        Sheet3.Range("t2").value = Application.WorksheetFunction.Sum(Sheet3.Cells(i, 1), Sheet3.Cells(i, 2))

    Next

    123:

    value = "0"
    Resume Next


    lastrow = wsClient.Cells.Find("*", wsClient.Range("F1"), xlFormulas, xlPart, xlByRows, xlPrevious, False).row
    For i = 2 To lastrow


        If Sheet3.Cells(i, 20) > 0 Then
            wsClient.Cells(i, 19) = "Yes"
        Else
            wsClient.Cells(i, 19) = "No"
        End If
    Next i

End Sub
