Cannot create triggers in a newly created template

[marius]

I tried {{HOSTNAME}:vfs.fs.size[/,free].last(0)}<10000, and {templatename:vfs.fs.size[/,free].last(0)}<10000, and I'm getting errors for both.

1.1beta8.

EDIT: turns out it was because i didn't have the corresponding item defined in the template.
