Permissions Error

So I am getting this error with my permissions when Bukkit starts up:

Server permissions file permissions.yml is not valid YAML: while parsing a block mapping in "<reader>", line 4, column 5: default: false ^
expected <block end>, but found BlockEntry in "<reader>", line 6, column 5: - '-essentials.backup' ^

I am running the latest 3.X permissions plugin and here is my code for permissions.yml
Any ideas on how to fix this?

Code:

Why are you using Permissions? It's dead, use a BukkitPerms manager like PermissionsBukkit, PEX or bPermissions
