I have in the process of XHTML validating my code and the W3C validator is presenting the following error:
Line 92, Column 142: general entity "itemid" not defined and no default entity.
This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.
&some_text&itemid=1" title="some text
Even though they provide an explanation, I really don't understand where I am going wrong. Please could anyone advise further?
