Get stored value from existing item in dictionary

[YasserKhalil]

Hello everyone

I am trying the following code

Sub Test()
    Dim a, dic As Object, s As String, i As Long, j As Long
   
    a = ThisWorkbook.Worksheets("Sheet1").Range("A1").CurrentRegion.Value
    a = Application.Index(a, Evaluate("ROW(1:" & UBound(a, 1) & ")"), [{3,7,13,14,15,16,17,18,19,20,21}])
   
    Set dic = CreateObject("Scripting.Dictionary")
    dic.CompareMode = 1

    For i = LBound(a) To UBound(a)
        s = a(i, 1) & vbTab & a(i, 2)
        If Not dic.Exists(s) Then
            dic.Add s, s
           
            For j = LBound(a, 2) To UBound(a, 2)
                If j = 1 Or j = 3 Or j = 6 Or j = 9 Then
                    If i > 1 Then a(i, j) = CLng(Application.WorksheetFunction.WorkDay(CDate(a(i, 1)), IIf(j = 1, 0, Val(j / 3))))
                End If
            Next j
        Else
            'Need Here Some Help
            Stop
        End If
    Next i
   
End Sub

What I need to add in this code is to detect if the item existing in the dictionary or not
If new then some calculations will be done ..on columns M to U
And if it is already exists, there is no need to do the calculations again .. just bring the results from the existing

run the above code and have a look at a(7), you will find it empty as it is already existed before
What I need for a(7) for example [This is a duplicate one] >> So I need to take the results in a(7,3) to a(7,11) from existing item
The exisitng item or the first instance of 20/04/2009 and "N" was in a(6)
So I would like to fill a(7,3) to a(7,11) with the same values in a(6,3) to a(6,11)
