Logic Hook not accessing directory

[Secret_Agent_99]

Hi All,
Sugar version 5.5
PHP version 5
Mysql version 5.0.51a

I have a problem, I don't know why my directory within the logic_hooks.php file not accessing its directory.
I made sure to copy the exact directory on the server.
logic_hooks.php Code:

 <?php
      if(!defined('sugarEntry') || !sugarEntry) die('Not a Vaild Entry Point');
      $hook_version=1;
      $hook_array= Array();
      $hook_array['after_retrieve']= Array();
      $hook_array['after_retrieve']= Array(1, 'SalaryCustomFunction', 'custom/modules/moduleName/fileName.php', 'SalaryCustom', 'SalaryCustomFunction');
      echo "LogicHook ";
    //this is echo out on the screen
?>  

The logic hook file is being called as it is echoing onto the screen.
The fileName.php code:

 <?php
 //code goes here
  
?>  

None of the code within readVacation.php file is being called. This is my confusion.
Any ideas why????

Thanks

Missed the hook_array['after_retrieve'][]
