Hello,
1 – You did a lot of copy/paste of HTML code. Your website’s HTML code is broken. Check your site with http://validator.w3.org/ to learn more (you made 1417 HTML errors). You can’t just copy/paste from anywhere (in example from Word).
2 – The form is there when you click “Llenar formulario’ tab.
3 – Do you have some widgets there? Maybe they can appear because of problems from point 1.
Thanks
Milos
