Hello
The code below worked fine until I decided to add something. (original code
is from the RonDebruin site)

What I wanted to add was if the following cells are blank -
a message box telling person to complete any cell(s) that is highlighted in
yellow
when I run the macro I get error 400 - cells that I want included are in the
macro below.

Sub Mail_ActiveSheet()

'Working in 2000-2007
Dim FileExtStr As String
Dim FileFormatNum As Long
Dim Sourcewb As Workbook
Dim Destwb As Workbook
Dim TempFilePath As String
Dim TempFileName As String
Dim OutApp As Object
Dim OutMail As Object

Set TestRange = Range("C11,E14,F9,F37,H6,M18,R14,S9,S10,S11,T37,AP 18,Y18,")
For Each cell In TestRange
If cell.Value = "" Then
'MsgStr = MsgStr & cell.Address & " "
End If
Next

If MsgStr < "" Then
Msg = MsgBox("All cells highlighted in yellow must be completed")
Exit Sub
End If
