Web to Lead/ Contact forms not working

Web to Lead/ Contact forms not working

Both these forms are not working as an integration with google sites. 

I am trying to publish the form to the Google Sites

1. I have a free account
2. I am trying to embed the web to lead form in my google site.

the form does not get published at the weblink that i provide, when i try to delete the form, it asks if the form should be deleted from the "marketplace" google site?

Looking for an urgent resolution to the issue.
