Differential Backup did not work

Hi all,
I've been using this stored proc to do full and log backups for a while
and it's working perfectly. Now, the requirements have changed I've to
run full backup at 7:00PM and differential at 5:00AM. The full and log
backups are still working not differential. Something is wroing in my
codes on differentail backup task.
Thanks so much,
Silaphet,
Here is the error report from the job history:
Executed as user: NT AUTHORITY\SYSTEM. Incorrect syntax near the
keyword 'TO'. [SQLSTATE 42000] (Error 156). The step failed.
Below is my stored proc code:

GOUnder the section "IF @.Full_Tran = 'DIFF'", it should be:
BEGIN
SET @.cmd = ' BACKUP DATABASE ' + @.db_name + ' WITH DIFFERENTIAL '
END
Remove the extra + sign and add a space before the word "WITH"
