Student Access to Cloud Assignment Denied

[steinert]

I am trying to use the External Tool to set up a Google Docs Cloud Assignment, so students can enter their answers into a document and submit it to me to be graded. The problem is that students are being denied access to the document. How do I fix this? When they request access, I get no message asking me to grant them access, but that's another problem altogether...
