Error parsing YAML

My plugin is throwing an InvalidConfigurationException on its file messages.yml. I've combed through it a thousand times and can't find any spacing or quotation problems so I obviously must be missing something.

Here is the error I'm getting, minus the stack trace:

Code:

ERROR:

balance: "&6You have %AMOUNT% go ...
^
expected <block end>, but found '<block mapping start>'
in "<unicode string>", line 16, column 5:
usage: "&7Usage: /deposit <amoun ...
^

And here is my full messages.yml:

Code:

1 ################################################################################

I marked the errors.
