NameError: 'fileIO'

[ChrisWhee1er]

First off, THANK YOU! I been looking for a cog like this a long time! And the code reads like it's even better than Mee6's version for sure. But I can't get it to run properly ;<
I'm able to get the Cog to run, but half of the script wont work, since it's unable to perform half the commands.
It's probably user error , but I even located the dataIO file and see that the name fileIO is defined.. What could be the issue causing it to NOT be defined in the main Levels cog?
Thanks for any support!
