trq Posted November 6, 2011 Share Posted November 6, 2011 It's saying the id "order" is already somewhere else in the document. Link to comment https://forums.phpfreaks.com/topic/250542-understanding-validator-message/#findComment-1285413 Share on other sites More sharing options...

haku Posted November 6, 2011 Share Posted November 6, 2011 I'm not sure what your reply refers to. But you can only use IDs once on a page. View the page source (HTML output) of your page, and do a search for the ID in question - you have to elements with the same ID.
