This morning I uploaded a new version of my WordPress Google Form plugin.  This update addresses the three items I noted in this post.  I also expanded the Test Bed Form I have  been using to develop and test the plugin.  If you’re curious, I have added the form to a page on this site.  If you run into a combination that isn’t working and I haven’t accounted for it in the test bed, please let me know and I’ll update my form.

I think I finally have Check Boxes working correctly.  They were a challenge because how PHP (which WordPress uses) pass arrays of information and Python (which Google Forms use for processing) are very different.  Thanks to a tip on the WordPress Hackers Mailing List to a utility called http://httpbin.org I was able to get my plugin to pass the parameters as Google expects them and everything seems to be working correctly.  The update should appear in your WordPress Dashboard fairly soon.
