What is needed to make this .bat file backup sql server 2005 database?

I have the following code in a file called mssqlscript.bat and what i want to do is simply double click it and have it run the backup.  It currently doesn't do anything when I double click it.  These same commands work fine when I use them in the sqlcommand line.  I assume that I will have to add username and password, etc., but I don't know the syntax.Start Free Trial
