Problem with piwik_action_name and PHP

Hello (sorry for my bad english),

if i put a php variable in “piwik_action_name”, i have no statistics with this variable in the vPage view.

Here is the end of my code in my php page

Thank you

  <?php  
   //$visitpage=$row['titre'];
   $visitpage='prout';
  
   } 
  
  ?>

</table>


 <?php

  mysql_free_result($result);

?>

Ok the problem was the quotes !

Bad syntax :
piwik_action_name = “<?php echo $visitpage; ?>”;

Good syntax :
piwik_action_name = ‘<?php echo $visitpage; ?>’;
