I've filled the grid bar 24d and 38a. I have all their crossing letters but just can't a) solve either of them, or b) see a possible letter for their intersection. I've searched Chambers with both their letter patterns but it's not giving me any options that would satisfy their intersection. I suppose my question is 'are both solutions in Chambers?' If so, I must have gone wrong with one of the crossing solutions (although I've double-checked them all). No other hints at this stage please. Thanks.
