Hmmm. Went there. Was referred to a file called *Errors.py* in Formulator. 
File doesn't exist. Noticed the thread was recent and the author was the 
author of the program. What did I miss?!

Thank you! Yes, finally!

Okay, now I'm confused. What is this for?

I did rewrite it.

Also, any idea on how to send *two* emails with slightly different content,
