Plugin Help Quick Queston

Hello,

I hope your all having a good evening, I have a quick question. After recently purchasing a custom crates plugin (one where you can receive keys and right click on the chest and get a random reward) I've been getting this error in consolve preventing it from working.

Code:

[22:14:39 INFO]: [CrateKeys] Enabling CrateKeys v0.5
[22:14:39 ERROR]: Cannot load plugins\CrateKeys\config.yml
org.bukkit.configuration.InvalidConfigurationException: while scanning for the next token
found character         '\t' that cannot start any token
 in "<string>", line 71, column 32:
          - eco give %player% 50000
                                   ^

This is the part of the config that's giving the error

Code:

    '9':
      percent: 10
      playerMessage: 'You opened a Voter Crate and received a $50,000!'
      broadcastMessage: []  
      commands:
      - eco give %player% 50000 

 

Code:

found character        '\t' that cannot start any token

This part of the error means that there is a tab in your file. YAML files cannot contain tabs.
