Question Why Is my Pex not working!?

I'm a bit of a Pex noob so hopefully someone can help me...
My question is, how do I use pex and WorldGuard to allow a certain group/groups to build in a certain region without having to be opd. Do I have to install modify world or not? and how would I go about putting it in the permissions.yml.
I also have 3 worlds (multiverse) so I dont know if thats affecting it?...

Here is my current Permissons folder: http://pastebin.com/zJem1R0z

 

You can do this with world gaurd.

I think this: https://bukkit.org/threads/how-to-use-the-entry-group-flag-in-worldguard.124066/
And this: https://www.spigotmc.org/threads/worldguard-group-entry-flags.52205/

Anyway, here's what I've found from the threads:

1) Define your region using /rg define <regionName>
2) Use the entry deny flag using /rg flag <regionName> entry deny
3) Add groups you want to have access to that area by using /rg addmember <regionName> g:<GroupName>

The steps 1-3 were found in Tom_'s post (the 9th one on the page).

Tell me if it doesn't work.

 

Thanks for the help but I want everyone to be able to enter the region I just don't want normal members to be able to build because its a spawn area. Do you know if there is a way to do that?

 

ok, I know it has something to do with this: http://wiki.sk89q.com/wiki/WorldGuard/Regions at the very bottom. you can define the owners of the region with this: /region define <region name> g:<pex group> and i beleive that will allow the builders to do that. Tell me if it helps.
