Hi,

I have below VBA code where I have a range under "Summary" sheet column D and Lookup Table("Lookup") range column A:B and return the value to Summary Sheet Column C:C..

Basically vlookup(Summary (D:D), Lookup Table ("Lookup")A:B,2,False). Can anyone help me modify the code. Not sure why its returning blank.

VBA Code:
Sub VlookupVV()
    OptimizeVBA True
    Dim startTime As Single, endTime As Single
    startTime = Timer
    Dim sWb As Workbook
    Dim fWs As Worksheet, sWs As Worksheet
    Dim slRow As Long, flRow As Long
    Dim pSKU As Range, luVal As Range
    Dim lupSKU As Range, outputCol As Range
    Dim vlookupCol As Object
    Set sWb = Workbooks.Open("C:\Users\dokat\OneDrive - \Power BI\Trade Report\Montly Data\Segment Lookup Table.xlsx")
    Set sWs = sWb.Sheets("Lookup")
    Set fWs = ThisWorkbook.Sheets("Summary")
    slRow = sWs.Cells(Rows.Count, 1).End(xlUp).Row
    flRow = fWs.Cells(Rows.Count, 4).End(xlUp).Row
    Set pSKU = sWs.Range("D4:D" & slRow)
    Set lupSKU = fWs.Range("D4:D" & flRow)
    For i = 2 To 2
        Set outputCol = fWs.Range(fWs.Cells(3, i), fWs.Cells(flRow, i))
        Select Case i
            Case 2
                Set luVal = sWs.Range("B4:B" & slRow)
          
        End Select
    'Build Collection
       Set vlookupCol = BuildLookupCollection(pSKU, luVal)
    'Lookup the values
       VLookupValues lupSKU, outputCol, vlookupCol
    Next i
    endTime = Timer
    Debug.Print (endTime - startTime) & " seconds have passed [VBA]"
    OptimizeVBA False
    sWb.Close False
    Set vlookupCol = Nothing
End Sub
Function BuildLookupCollection(categories As Range, values As Range)
    Dim vlookupCol As Object, i As Long
    Set vlookupCol = CreateObject("Scripting.Dictionary")
    For i = 1 To categories.Rows.Count
        vlookupCol.Item(CStr(categories(i))) = values(i)
    Next i
    Set BuildLookupCollection = vlookupCol
End Function
Sub VLookupValues(lookupCategory As Range, lookupValues As Range, vlookupCol As Object)
    Dim i As Long, resArr() As Variant
    ReDim resArr(lookupCategory.Rows.Count, 1)
    For i = 1 To lookupCategory.Rows.Count
        resArr(i - 1, 0) = vlookupCol.Item(CStr(lookupCategory(i)))
    Next i
    lookupValues = resArr
End Sub
Sub OptimizeVBA(isOn As Boolean)
    Application.Calculation = IIf(isOn, xlCalculationManual, xlCalculationAutomatic)
    Application.EnableEvents = Not (isOn)
    Application.ScreenUpdating = Not (isOn)
    ActiveSheet.DisplayPageBreaks = Not (isOn)
End Sub

Don't know about VBA but your VLOOKUP syntax looks wrong. The lookup should be one value not a range like Summary(D:D) seems to be
