I really like the look and ease of editing the new Chooser sample script, but I'm a newbie and I don't know where to take it next. I've added all of my boot options to the run_me script, but I don't see where it actually executes a command here is an extract:

set kernel.1.name = "Dell 32bit Diagnostics"
set kernel.1.msg.0 = "This will run the diagnostic system created by Dell for Optiplex's. "
set kernel.1.value = "memdisk images/DellDiag.ima.gz"

now is there a variable in chooser.cds that I have to add to make this script actually run my command?
