Struggling a bit this month, despite doing it multiple times, page 17 Code Breaker.
- The letter x should read as . . .
- or maybe what is the letter represented by 10
- or so I can see where I have gone wrong 23 down a seven letter word reads as

Not getting an answer frustrates me, any help with this answer would be much appreciated but always like to know where I have gone wrong.

Many thanks in advance.
