localization strategy and variables

Any suggestions? I messed with it for a bit but it wouldn't launch from the iPad.  Need some insight on ioslaunch.html perhaps. I tried leaving tincan.xml in the root and created an intermediate story.html with links to the story.html files inside of the language-specific directories and the LRS accepted the package and launched my story.html file but when it came to ioslaunch.html it failed giving "Cannot access content. AMP cannot access this content" error so messed with ioslaunch.html to try to incorporate the subdirectory into the launch path but don't know what I'm doing instead getting "AMP cannot download the content because one or more files cannot be found" and gave up. Thanks
