VBA Publishing temporary HTML file, run time error 1004

[samfraser3]

Hi all

Updating someone else's VBA (no longer at company so cannot ask them!) and I keep getting this error, it is one of the very last stages of a long macro that autopopulates a number of emails. I gather the error is likely due to an undefined path/file name but I have not worked much with temporary files and the publish to HTML so I am lost, any help would be appreciated!

Function RangetoHTML(rng As Range)

    Dim fso As Object
    Dim ts As Object
    Dim TempFile As String
    Dim TempWB As Workbook


    TempFile = Environ$("temp") & "\" & Format(Now, "dd-mm-yy h-mm-ss") & ".htm"


    'Copy the range and create a new workbook to past the data in
    rng.Copy
    Set TempWB = Workbooks.Add(1)
    With TempWB.Sheets(1)
        .Cells(1).PasteSpecial Paste:=8
        .Cells(1).PasteSpecial xlPasteValues, , False, False
        .Cells(1).PasteSpecial xlPasteFormats, , False, False
        .Cells(1).Select
        Application.CutCopyMode = False
        On Error Resume Next
        .DrawingObjects.Visible = True
        .DrawingObjects.Delete
        On Error GoTo 0
    End With


    'Publish the sheet to a htm file


    With TempWB.PublishObjects.Add( _
         SourceType:=xlSourceRange, _
         Filename:=TempFile, _
         Sheet:=TempWB.Sheets(1).Name, _
         Source:=TempWB.Sheets(1).UsedRange.Address, _
         HtmlType:=xlHtmlStatic)
        .Publish (True)
    End With


    'Read all data from the htm file into RangetoHTML
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set ts = fso.GetFile(TempFile).OpenAsTextStream(1, -2)
    RangetoHTML = ts.readall
    ts.Close
    RangetoHTML = Replace(RangetoHTML, "align=center x:publishsource=", _
                          "align=left x:publishsource=")


    'Close TempWB
    TempWB.Close Savechanges:=False


    'Delete the htm file we used in this function
    Kill TempFile


    Set ts = Nothing
    Set fso = Nothing
    Set TempWB = Nothing
End Function
