I looked at the code noted by stevenc330599:
While his code is indeed different from mine, somehow my "customized" code is the same as the original .php file.
Now, I have down so much to these files that I don't know where I am anymore. Not only does the edited php not send email anymore, but now the one that was working last night doesn't work either.
I think I'm close to dropping back and punting (starting from scratch). I did not expect to put two solid days into this form.
