Yep - you're spot on there teacher1. Thanx for that, I was obviously going along the wrong lines.
It's actually in a union magazine my husband gets every quarter. There are always 3 different crosswords all with unusual type clues, that's why I like it so much. One has this type of clue, one has like a story with missing words to find with clues, and the third has misprints in the clues, (although the clues still make sense), and the letters that are wrong in them all spell out a phrase that is given at the top. It normally takes me a while to finish them, but this is the first time i've been stumped!
Thanks again for your help.
