Plugin Help Pex permissions.yml issue

Hey everyone I am need of assistance with my pex permissions.yml file. I recreated it multiple times and I believe everything is correct although whenever I startup the server or reload the pex plugin I get this error:
org.bukkit.configuration.InvalidConfigurationException: while parsing a block mapping
I don't know valid YAML so if someone could just go over and review my permissions.yml and show me the errors, that would be awesome. I will post the full console feed of the error and if someone knows what's going on I can post the permissions file as well

Code:

Here is permissions file anyways:

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

In line 137, the permission needs to be vertically in line with those other permissions below it.
