Importing multiple CSV files into multiple worksheets in Excel using VBA

Question

I am working to create a VBA/macro that imports 2 CSV files from a specific folder into 2 worksheets in an Excel template that I have created.

To be more specific, these files are created and saved as new workbooks on a daily basis (two new files being added into the folder everyday) so my problem is how to code my macro to always import the 2 latest files?

Please see below the code from which I manually select and import the latest files using macro. However, re-running the macro does not work as it shows "run-time error '5' - invalid procedure call or argument". Your help would be much appreciated.

You can find the latest file(s) this way:

EDIT: Dir return only the filename, so you need to append the path, too.

EDIT2: As per user request a few Debug.Print is inserted.

Sub main()
    Dim s1 as String, s2 as String

    s1 = LastFile("P:\APS\Reports_From_PDP\AP_PDP_VehicleLoad_Report_AM")
    Debug.Print "Last file1: " & s1
    s2 = LastFile("P:\APS\Reports_From_PDP\AP_PDP_VehicleLoad_Report_PM")
    Debug.Print "Last file2: " & s2
End Sub
Function LastFile(sName as String) as String
    Dim dLatest as Date
    Dim dFound as Date      ' date of one matching filename
    Dim sLatest as string   ' the latest file or ""
    Dim sFound as string    ' one matching filename
    Dim sPath as string

    dLatest = 0
    sLatest = vbnullstring
    sPath = Left$(sName,  InStrRev(sName, "\"))

    sFound = Dir(sName & "*.csv")
    Do While sFound <> vbnullstring
         Debug.Print "Found: " & sFound
         dFound = FileDateTime(sPath & sFound)
         If dFound > dLatest Then 
             dLatest = dFound
             sLatest = sFound
         Endif
         sFound = Dir
    Loop
    LastFile = sLatest
End Function
