I am trying to send an email in one of my solutions using Web Direct 13. I have an email address in the To: and Cc: sections and a calculation for the Subject and Text in the Message. When I run the Send Mail script, the To: email address is blank and the subject goes up into the Bcc: Section. The only thing that work is the Cc: email address and the message.
Can you show us the script here? I assume it is not trying to send via Client Email. Make sure the script step is using SMTP Server and correctly configured. Does it work from a FileMaker Pro client and only fails on Web Direct?
