svn over apache2 logging problem

[Keva-Slient]

here is my config in dav_svn.conf:
<Location /svn>                                                                 
                                                                          
    DAV svn                                                                     
                                                                          
    SVNParentPath /wns/data/svn                                                 
                                                                
    SVNListParentPath On                                                        
                                                                     
    AuthType Basic                                                              
                                                                       
    AuthName "Subversion Repository"                                            
                                                             
    AuthUserFile /wns/etc/apache2/dav_svn.passwd                                
                                                       
    Require valid-user                                                          
                                                               
</Location>                                                                     
                                                                                
                                                            #CustomLog 
/var/log/apache2/svn_logfile "%{%Y-%m-%d %T}t %u@%h %>s repo:%{SVN-REPOS-NAME}e 
%{SVN-ACTION}e (%B Bytes in %T Sec)" env=SVN-ACTION                             
                         
CustomLog /var/log/apache2/svn_logfile "%t %u %{SVN-ACTION}e" env=SVN-ACTION    




all of the log settings are not working.
it only creates log file. there is not any content written when i commit , 
checkout or update.
why is this?
