Google Docs is Still Waiting – Help

Hello,

I've tried to create my first Timeline JS but I felt on a bug with a turning wheel telling me that : "Google Docs is still waiting"

Here is the link to my google spreadsheet,

https://docs.google.com/a/uclg.org/spreadsheet/ccc?key=0Ao21a08PvgWUdGhQbDlQdWJLQUh2UmJSZmlGdnE3ZEE#gid=0

Tell me if you can solve this problem

Thanks
