I am attempting to implment the code for automysqlbackup available on this site - http://themebot.com/articles/tips-and-tutorials/how-to-have-automatic-backups-of-your-mysql- database but I receive the following error message:
PHP Parse error: syntax error, unexpected '=' in /var/www/vhosts/mysite is entered here/httpdocs/cronTasks/automysqlbackup.php on line 29

Line 29 is the standard first line of code:
Line 28 # Username to access the MySQL server e.g. dbuser
Line 29 USERNAME="username is here"

What am I doing wrong?

Sorry for the late reply. Did you ever get this working?
