Magento

Exactly the same question about “right” and “left” in checkout.xml because there is no change at my page.
I wrote it at Comments of webinar.

Thank you all for the help.

Hi there asfalta ;
I saw this on another post, it should help :

Go to menu entry: Admin > System > Cache Management, and make sure that all are Disabled when you are developing or making changes to config or layout files.
