Issues with creating jobs in Enterprise Manager

I've created a job to run a differential backup on a database. I've used the TSQL script generated by SQL Backup. Here's the resulting script:

master..sqlbackup '-SQL "BACKUP DATABASE [DBMon] TO DISK = ''F:\SQLDump\SQLBackup\DIFF_MNFOODS_DBMon_<DATETIME yyyymmdd hhnnss>.sqb'' WITH NAME = ''Database (DBMon), 7/20/2005 10:36:39 AM'', DESCRIPTION = ''Backup on 7/20/2005 10:36:39 AM Database: DBMon Instance: MNFOODS Server: SERVER'', DIFFERENTIAL, COMPRESSION = 1" -E -I MNFOODS'

Here's the error it produces when testing with query analyzer:

Output from SQL Backup (3.2.0)

Msg 3013, Level 16, State 1, Server SERVER\MNFOODS, Line 1

(10 row(s) affected)

I need to populate the "<DATETIME yyyymmdd hhnnss>" portion of the file name so it works with SQL. I would also like to populate the current date in the "Name" and "Description" areas of the script.

Any help would be appreciated.

Thank you!
