Firstly, I think you've done a fantastic job on this - I'm super-impressed!

Unfortunately, however, the thing I really wanted this for (to be able to create dynamic charts I could then embed into a blog) isn't working (for me).

I create the chart, and then press publish in the bar above the chart, but nothing happens... I've set sheet.zoho.com and *.zoho.com into my 'trusted' websites (as the company I work for has some quite harsh security settings on 'normal' websites).

Any ideas how I can start getting urls?

Cheers!!!
