When trying to use a token variable as a default answer, by entering {TOKEN:firstname} (In capital letters, small letters, first capital, with or without curly brackets,...) , the result is an empty field or
<span class='em-expression em-haveerror'><span title='Undefined variable' class='em-error'><span title='Undefined variable' class='em-var em-var-error' >TOKEN:Firstname</span></span></span>.
This while expecting the firstname which was entered during registration.
