embed form on FB page

Help I can't seem to embed the form.  Im missing a piece here!!! I have followed your video instructions step by step. When I get to the last part my page does not come up.

How do I get my page to come up so I may embed my form?

The page needs to have a tab added to it before it will allow for adding the form.

If that method is not working for you, there is an alternate method you can try:
