Newbie Question - Form to Post (Outputted post doesn't display all of the form)

By default, only the Post Body field will be added to your post. If you are collecting data in custom fields, you need to get those into the post body somehow. It's the same if you create a post in the post editor and add custom fields: they do not show up in the post.

To show the data collected by Gravity Forms in custom fields, in your post body, you can use the Content Template of the post body. On the Properties tab of your Post Body field in the form builder, find the checkbox which says "Create content template". Check that, and a text box will appear with something like this in it: {Walk Summary:2}

That is all Gravity Forms adds to your post by default. But by using the drop down, you can insert more merge tags into this Content Template, and have your custom fields appear in your post. You may have to add additional markup to get them to look just like you want: you have complete control.

Try that and let us know if you have any questions.

It is not done automatically. Just like when creating a post: anything added in a custom field is not automatically added to your post. How would the template know how to display your information?

There is no tutorial I know of other than the documentation which can be found here: http://www.gravityhelp.com/documentation/

However, it's very intuitive. Have you already checked the box "Create content template"? If so, you just need to add fields from the drop down, at a minimum, and you're done. You can dress it up from there, and we're happy to help you once you get started.
