Why do I only see code when I try to open my CODAP document from Google Drive?

If you see a bunch of code when you try to open your CODAP document from Google Drive, look for the text at the top/middle that says “Open with,” click on it, and select CODAP. If you do not see CODAP listed as an “Open with” option, try launching CODAP directly and then clicking on “Open Document” followed by “Google Drive.” See here for more instructions on how to open a saved CODAP file.
