Oh dear Methyl, you really are looking far too deeply into this one, aren't you love. You either know the answer or you don't. There was absolutely no need at all for you curt, abrupt response.

Hi Katburd - this one stumped everyone and I didn't find the answer until competitor's companion revealed it, so don' feel bad - I'm sure they'll be another one I get stuck on soon! thanks for you comments
