When I moved to Wordpress v3, I broke the code for the imbedded pdf files in various Wordpress pages. Since the hard links worked and the page threw an error "plug-in needed", I thought it was Safari and/or Adobe pdf reader that was at fault.
Not so. Tonight I switched to "Google Doc Embedder" and this code works. The related pdf file must be accessible via a URL, not simply stored in the Wordpress media database. Now all the forms show once again.
