The language string error seems to be linked to a Joomla! bug. I'm not clear if there is also a ChronoForms bug that csues this too. The main fix seems to be to make sure that in your Joomla! site configuration the From Email address domain matches the site domain.
Ok, for now, I'll live with it, it seems to work, even though the error is shown. I've set up the mailaddresses correctly to match the domain, and the mailaddress is working, so, that part is ok.
For the label:value problam I'm not completely sure what you want. Usually the easiest solution is to look up the missing data again after the form is submitted. Or you can use a script to copy the missing part into a hidden input when the select box changes.
Well, the dropdown box in the form is like this:
Formand:formand@dkdb.dk
Kasserer:kasserer@dkdb.dk
Webmaster:webmaster@dkdb.dk
When one of these are selected, the value is used in the mail address, so I only have one form, for several receipients.
What I think would be nice is the mail I send to the user using the contact form I could write:
"You've sent a mail to Formand" or something like that.
I don't want to write:
"You've sent a mail to [email]formand@dkdb.dk[/email]" because I don't want to reveal the addresses.
Currently it just says "You've sent a mail" :-)
