Please refer to the image below. I need to save the data from column "Total Qty" in a certain folder with the file name "Shipment ID" and copy it to another workbook. Here, I think back to that file and get data from it for a different column.


I need to add one more item to this, namely, I want to confirm whether the file is present in the particular folder or not. Update the file if it already exists. Create a file using the "Total Qty" field if the file doesn't already exist.
For this, I created the code listed below. It worked up till I set the column "total qty "functions to "=(G2+H2)". The destination file displays "=(#REF!+#REF!)" in cells after the function has been entered.
Sub Export_Total_Qty()
    Application.ScreenUpdating = False
    Dim FilePath As String
    Dim ID As String, abc
    Const FILE_INFO As String = "D:\Excel Software\Shipment Tracking\Junk\<id>.xlsx"
    ID = Worksheets("Sheet1").Cells(1, "O").Value
    abc = Replace(FILE_INFO, "<id>", ID)
    FilePath = ""
    On Error Resume Next
    FilePath = Dir(abc)
    On Error GoTo 0
    If FilePath = "" Then
         Sheets("Sheet1").Range("I2:I50").Copy
         Workbooks.Add
         ActiveSheet.Paste Destination:=Range("A1")
         ActiveWorkbook.SaveAs _
        Filename:=abc
         MsgBox "New Entry is created, Thak you", vbInformation, "Kutools for Excel"
    Else
        Sheets("Sheet1").Range("G1:G50").Copy
        ActiveSheet.Paste Destination:=Range("A1")
        'ActiveWorkbook.Update _
        Filename:=abc
        MsgBox "successfully Updated", vbInformation, "Kutools for Excel"
    End If
    Application.ScreenUpdating = False
End Sub
