Hi Trevor and Mamya,
On many occasions, I've identified at least 2 or 3 possible answers for a given clue in the Saturday Daily Record...each of valid currency!
On these occasions I enter the most logical answer but then 'cover all bases' by highlighting the other possible answers in red ink at the top of the grid and saying 'take your pick!'
Some weeks the clues are pretty tenuous....I'm convinced that the setter is smoking some exotic material :o)
