VBA to select a Range of cells as Email Body In Outlook

I really could do with some help.

I am trying to send the info from cells A1:G38 as the body of my email.

I need two options to send the same data one for a day shift and one for a night shift this is due to the automated subject line.

The code sends the email just the body of the email is always blank any ideas? Also when I add the second function (Night shift) using the same code as I used for the (day shift) the macro doesn't run at all?

I am new to VBA but enjoying the challenge.

Thank you in advance.

This is the code I am using, and I have attached the excel spreadsheet.

Sub CommandButton99_Click()

Today = Format(Now(), "[$-F800] dddd, mmmm dd, yyyy")
 
    Dim rng As RANGE
    Dim OutApp As Object
    Dim OutMail As Object

    Set rng = Nothing
    On Error Resume Next
    
    
  Set rng = Sheets("Sheet1").RANGE("A1:G38").SpecialCells(xlCellTypeVisible)
    On Error GoTo 0

    If rng Is Nothing Then
        MsgBox "The selection is not a range or the sheet is protected" & _
               vbNewLine & "please correct and try again.", vbOKOnly
        Exit Sub
    End If

    With Application
        .EnableEvents = False
        .ScreenUpdating = False
    End With

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    On Error Resume Next
    With OutMail
        .To = "XYZ@XYZ.com"
        .CC = ""
        .BCC = ""
        .subject = "PLC SUPPORT SHIFT REPORT Days" & Today
        .HTMLBody = RangetoHTML(rng)
        .Send
    End With
    On Error GoTo 0

    With Application
        .EnableEvents = True
        .ScreenUpdating = True
    End With

    Set OutMail = Nothing
    Set OutApp = Nothing
End Sub


Function RangetoHTML(rng As RANGE)

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

    TempFile = Environ$("temp") & "\" & Format(Now(), "[$-F800]dddd, mmmm dd, yyyy").HTM

        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

   
    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

   
    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=")

    
    TempWB.Close savechanges:=False

   
    Kill TempFile

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