Controlling Remote Controlled Sockets (SC2262 emulation by Arduino)

In order to start to ply with this project I've tried to upload the code as is, with the TX unit connected, but i'm getting a verify error on the code, I've looked through it but can't understand why it's having an issue with the array on line 121, error:

sketch_nov22a.ino: In function 'void sendOneSC2262Packet()':
sketch_nov22a:121: error: switch quantity not an integer
sketch_nov22a.ino: In function 'void loop()':
sketch_nov22a:270: error: incompatible types in assignment of 'char' to 'char [13]'.

Is anyone able to point me in the right direction?

Many thanks,
Stuart.
