Mistaken XHTML Validation Issues

When I try to validate my document (www.mastermade.biz/new) I receive the
error
(http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fwww.mastermad
e.biz%2Fnew%2Findex.php):
  

Target: http://www.mastermade.biz/new/index.php


Please, validate your XML document first!

Line 53

Column 24

Element type "a" must be followed by either attribute specifications, ">" or
"/>". 

 

However, there is no <a> tag on line 53. Additionally, the document
validates fine XHTML 1.0 Strict Validator
