I think your validator may be faulty ????

The address of the page being checked is

 

http://www.trainingon.net/

The error being reported is

1.                              ErrorLine 44, Column 286: there is no
attribute "valign".

..8281250" alt="Expand Courses" valign="middle" /></td>

 

But, this text does not appear in the document at all. However, an element
style style="vertical-align:middle" does exist and I think your parser is
translating this and outputting the error shown.

Perhaps you could let me know if this is a checker error ?
