Thank you for your answer Takayuki!
I have read it but I don't really understand it.
Do I need to add some code if I want to show the textBOX email field into the contact form?
As you see in the link http://www.o-dvision.com/front/contacts/ the textbox is not showing. If I need to add code, in which field do I need to do that?
Thank you so much for your help, I appreciate it! And so sorry because I don't know so much about programming!
Best regards!!
