Hi All, I am trying to create an index that returns something like 1,2,1,2,3,4,3,4,5,6,5,6,7,8,7,8 and so on and so forth until a predetermined value (which is obviously even). I am trying very hard to avoid for loops or for loops front ends. I'd be obliged if anybody could offer a suggestion. BW F
