I found a bug in FormMail v 8.11 while setting up my form to send results as an HTML e-mail. I followed the instructions on this page.
The bug is that fields with a hyphen (-) will not display properly in the HTML e-mail.
For example, I have a field in my form named "manager-name". Thus, in my HTML e-mail template, I reference $manager-name, since that is the name of the field. This is interpreted incorrectly by the script as $manager. The e-mail sent by the script shows N/A-name (where the text "N/A" is specified by TemplateMissing=N/A) rather than the real data specified by field $manager-name.
I am wondering if there is a bug fix for this in later versions.
