How to attach multiple emails using PT_MCF_Mail

I am trying to attach multiple files to an email using application package PT_MCF_MAIL.  I have had some success in that the email is being generated. I am able to attach a file to the email.  The issue is that it is attaching the last file it finds in the directory twice rather than attaching each of the two files that are stored in the directory.  in my process, the files are not always named the same, they are not always in the same location.  I have looping logic to find and load the file locations and names in arrays
