Apologies, Chrise, I am so sorry. I interpreted the rules as being that when you set a clue you can't offer a solution to the next clue (i.e. the one that your correct solver posed) until that becomes "open", but if someone solves it before then you are back in the game on subsequent clues
Didn't mean to spoil it for others; perhaps someone else can set one and I'll keep out of it for the time being.
