Please, more info
I take it that the "forms action page" form2mail.php?
And the form page - is it contact.php?
The instruction "select the form element, in the property inspector" I take it it is "Application" and "Bindings" - is that correct?
You loose me in the part where you say: "now select the form element, in the property inspector, click the lightning bolt next to initial value, expand the validated entries group and select the corresponding binding".
What corresponding binding am I looking for?
Thank you for your help
