adding comments to the bottom of a post

I have posted an entry and there is the button that says add contact form. I clicked that and have them put a name and a comment but I cannot get it to post on the bottom of the article when they do it. I went through and checked all the boxes that says anyone can post and unchecked any that says needs approval before showing but the comments section on the side will not post any comments as well as any comments on the bottom. Can you help please
