collective.pfg.showrequest shows field labels and values on the next form generated by PloneFormGen.
Sometimes, you might need to chain forms to create wizard like forms where you want to show field input results from the previous form. This package serves for this need by simply registering viewlet to plone.app.layout.viewlets.interfaces.IAboveContentBody interface.
Once you have quickinstalled collective.pfg.showrequest, go to the Form Folder (Form2) where you want to show the field results.
There is Show Request button under Actions, so click it. Input field ids from the previous form (Form1) and save it.
Copy the field types from the Form1 to the Form2 with default values and overrides empty.
You will see previous form results above the content body now like it is on thanks page.
If you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

[buildout] ... eggs = ... collective.pfg.showrequest
Re-run buildout, e.g. with:
$ ./bin/buildout
