End Sub

now i get "object doesn't support this property or method" when it gets to the CDO_Mail.Attachment = strAtch line ? most of the articles im looking at utilize outlook and not CDO. The link you posted was one article i've gone over and even downloaded his modules to go through them and try to decode them but what he has written down isn't notated very well to where someone as inexperienced as i can understand whats going on. all this is way over my head and why im asking for help.
