Permissions help!

Okay so I know how to use permission just not when I mess up, because I'm not sure what the difference would be between the mess up and normal So I was wondering if anyone could tell what I messed up Thank You! http://pastie.org/4456616

Reports:
ERROR:

while parsing a block mapping
in "<unicode string>", line 12, column 3:
Guest:
^
expected <block end>, but found '<block mapping start>'
in "<unicode string>", line 155, column 4:
Builder:
^

So my guess would be there's a problem on line 155
(If you look at it, it looks a bit odd compared to others)

 

I don't understand xD :3

 

Code:

  Trusted:
    default: false
   Builder:
    default: false

Tell me the number of spaces before Trusted and the number of spaces before Builder.
If you can find a difference, try making them the same.
I can tell you Trusted has the correct number of spaces.

 

Oh ^.^ Thank you this was helful
