Aha, that's it I haven't got my clues confused but my sister's writing is SO bad that her 4 looks like a 9!!!!!!!!!!!! I thought it was a strange clue and was trying to fit F or Fe in somehow. Haha!! If I'd spotted that I needn't have bothered anyone.
Thanks very much and Merry Christmas to all, though I might be back yet as I'm struggling with the biggy in the MOS now.
