Send round office a macro enabled ss

[Sean]

I have a Excel workbook and I want to email a sheet to collegues for them to
fill in and pass on for other to work on

code I have I have copied from another post and adapted

Sub Mail_ActiveSheet()
'Working in 97-2007
Dim FileExtStr As String
Dim FileFormatNum As Long
Dim Sourcewb As Workbook
Dim Destwb As Workbook
Dim TempFilePath As String
Dim TempFileName As String

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

Set Sourcewb = ActiveWorkbook

'Copy the sheet to a new workbook
ActiveSheet.Copy
Set Destwb = ActiveWorkbook

'Determine the Excel version and file extension/format
With Destwb
If Val(Application.Version) < 12 Then
'You use Excel 97-2003
FileExtStr = ".xls": FileFormatNum = -4143
Else
'You use Excel 2007, we exit the sub when your answer is
'NO in the security dialog that you only see when you copy
'an sheet from a xlsm file with macro's disabled.
If Sourcewb.Name = .Name Then
With Application
.ScreenUpdating = True
.EnableEvents = True
End With
MsgBox "Your answer is NO in the security dialog"
Exit Sub
Else
Select Case Sourcewb.FileFormat
Case 51: FileExtStr = ".xlsx": FileFormatNum = 51
Case 52:
If .HasVBProject Then
FileExtStr = ".xlsm": FileFormatNum = 52
Else
FileExtStr = ".xlsx": FileFormatNum = 51
End If
Case 56: FileExtStr = ".xls": FileFormatNum = 56
Case Else: FileExtStr = ".xlsb": FileFormatNum = 50
End Select
End If
End If
End With

' 'Change all cells in the worksheet to values if you want
' With Destwb.Sheets(1).UsedRange
' .Cells.Copy
' .Cells.PasteSpecial xlPasteValues
' .Cells(1).Select
' End With
' Application.CutCopyMode = False

'Save the new workbook/Mail it/Delete it
TempFilePath = Environ$("temp") & "\"
TempFileName = "Part of " & Sourcewb.Name & " " _
& Format(Now, "dd-mmm-yy h-mm-ss")

With Destwb
.SaveAs TempFilePath & TempFileName & FileExtStr, _
FileFormat:=FileFormatNum
On Error Resume Next
.SendMail "(e-mail address removed)", _
"Enterprise User Notification"
.SendMail "(e-mail address removed)", _
"Enterprise User Notification"
.SendMail "(e-mail address removed)", _
"Enterprise User Notification"
On Error GoTo 0
.Close SaveChanges:=False
End With

'Delete the file you have send
Kill TempFilePath & TempFileName & FileExtStr

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


and this works, but how do I when I open the email (still testing) fill in
the next part and email on. I have a control button with this macro attached.
