Don't understand how to use 2D char array arduino

//I am getting this error:
//Parsing:60: error: scalar object 'jsonFilter' requires one element in initializer

/*
 Sample sketch to demonstrate Multi Level JSON parsing in Arduino

 This sketch parses the complexly nested JSON

 Libraries needed:

 - aJson library for JSON parsing - https://github.com/interactive-matter/aJson

 Circuit:

    You don't need any circuit, but need the Arduino board
