Hello, Access 2013-Recurring Condition does not work with me, I convert the Macro to VBA to show you what I did
'------------------------------------------------------------
' TaskCovertto_VB_RecurringM
'
'------------------------------------------------------------
Function TaskCovertto_VB_RecurringM()
On Error GoTo TaskCovertto_VB_RecurringM_Err

    With CodeContextObject
        If (.RecurringCombo = 1) Then
            Forms!TaskF!DueDate = Forms!TaskF!DueDate + 1
            ' Daily
        End If
        If (.RecurringCombo = 2) Then
            Forms!TaskF!DueDate = Forms!TaskF!DueDate + 7
            ' Weekly
        End If
        If (.RecurringCombo = 3) Then
            Forms!TaskF!DueDate = Forms!TaskF!DueDate + 14
            ' BiWeeks, means 2 weeks
        End If
        If (.RecurringCombo = 4) Then
            Forms!TaskF!DueDate = Forms!TaskF!DueDate + 30
            ' Monthly
        End If
        If (.RecurringCombo = 5) Then
            Forms!TaskF!DueDate = Forms!TaskF!DueDate + 90
            ' Quarterly
        End If
        If (.RecurringCombo = 6) Then
            Forms!TaskF!DueDate = Forms!TaskF!DueDate + 360
            ' Annually
                End If
    End With


TaskCovertto_VB_RecurringM_Exit:
    Exit Function

TaskCovertto_VB_RecurringM_Err:
    MsgBox Error$
    Resume TaskCovertto_VB_RecurringM_Exit
