Hi everyone,

I'm a newbie in Drupal and got stuck to put a html form code on a page.
The form code is very simple (just email field and submit button).
When I put the code on a page, it just displays the actual plain text code, not the html form.
How can I put html code working on a page?

Please help~

Thanks guys!
Have a great day everyone!
