I am struggling a bit to get the sentence and the 2 instructions, possibly because I have the wrong extra word in some cases. So far I have 5 words at the start of the sentence (2, 2, 4, 4, 3) and 5 at the start of the instructions (6, 1, 4, 2, 6) but if those are right I have reached a dead end. Also is R the unchecked letter in 20 across? Confirmation that I am on the right lines would be much appreciated.
