Since I first added support for Multi-Page Google Forms I have had a sample form on my site with the submitted results displayed on another page. I use the Inline Google Spreadsheet Viewer plugin to display the submitted results on the page except it wasn’t working.
It worked fine for my Sample Form results but not the Multi-Page Form results. I finally figured out that I was using the wrong Google Docs key to display the results. I was using the key that Google Doc’s Share functionality provides instead of the key that the Publish to Web Page provides. It is this later key that allows the plugin to operate correctly. Doh! Need to read the documentation a little closer I guess.
