How can I output markup fields or descriptions in my Webform email? I have a webform that requires a markup field, or alternatively, a description to be carried through to the email or "View form submission" page.

Typically one can put the token %email_values in the email template which will give a list of fields and their labels that are submitted to the form - but this doesn't seem to include markup fields, or field descriptions.

I have tried using other tokens such as %post or %value. For instance, I have a markup field with machine name "foo" in a fieldgroup "bar", and putting %value[foo][bar] just dumps the string [foo] into my email. 

So is there a way to reference these parts of the webform?
Did you tried using this? If the markup field foo sits within the fieldgroup bar, you need to inverse the order and the last % shouldn't be there.

%value[bar][foo]
