Yes, sorry you are right, and now I have read the note at the bottom of that page. Sorry about that.
Anyway, I am trying to make it work using an input from another plugin. At the moment I am using the following link:
where $adcontact_name gives the user nicename generated by the plugin.
Unfortunately if I use it in the shortcode as follows it doesn’t work;
echo do_shortcode(“[fep_shortcode_new_message_form to=$adcontact_name subject=Re: $title]”);
Any ideas or help would be appreciated.
