Huge congratulations to Andrew Russell of Priestnall School, who was the first to email me the solution to this code (on September 27th 2016). And huge congratulations to Annabel Clarke, who also solved it.
To anyone else that has also solved it, well done too. It is very hard to solve intertwined codes, and anyone that has managed it is a superb code cracker.
