Trying to set certain permissions.

I recently started a basic survival server with no commands enabled through an option on the server hosting website.

A friend of mine asked if I could enable a /sethome, /spawn and /tpa. I started using essentials for the commands.

The problem is I only want those commands enabled. obviously I want the player to mine, to eat to attack and things a normal, AND the /tpa, /sethome and /spawn

Note I also want the sub parts of /sethome /tpa like /delhome.

Im using permissionex for permissions and I tried using "- - essentials" and then the commands I want enabled but it doesn't work.

Any tips/help completely appreciated

Many thanks,
The Ranger

P.S: Heres the command I used:

groups:
All:
options:
default: true
permissions:
- -essentials
- essentials.delhome
- essentials.spawn
- essentials.sethome.multiple
- essentials.sethome
- essentials.sethome.bed
- essentials.sethome.multiple.unlimited
- essentials.tpa
- essentials.tpaccept
- essentials.tpdeny
- essentials.home
