the plugin needs a check size of music files that are being uploaded

if i try to upload a mp3 thats bigger then what is set in admin 
i get this error


Fatal error: Call to a member function text() on a non-object in /home/thenaugh/public_html/ow_plugins/musicextreme/bol/service.php on line 41

the plugin should read the size of the music file and the size limit  then let user know the file is to big before the user even clicks upload
