Bukkit

Is there a way to set permission nodes for warmup/cooldowns such that players with the permission node have the cooldown/warmup and those without it don't? I tried this:

fix: command: /fix
type: COOLDOWN delaytimer: 10 success-message: "Item Repaired" permission-required: true permission: perm.fix

and giving the appropriate group the perm.fix permission node. But every time i tried the command, it came back and said i didnt have permission to run the command. I also tried giving the group -perm.fix and that gave the same resaults.

Thanks for the help!
