 Author Comment/Response lilly 04/18/12 5:22pm list question: to get my vocabulary straight. this is my LIST LIST={{{a,a,2},{b,b,-8},{c,c,7},{d,d,9}},{{a,a,1},{b,b,7},{c,c,-7},{d,d,2}},{{a,a,9},{b,b,8},{c,c,10},{d,d,7}},{{a,a,5},{b,b,1}, {c,c,3},{d,d,-9}}} within the LIST there are lists for example: list={{a,a,2},{b,b,-8},{c,c,7},{d,d,9}} in my list there are elements for example: element={a,a,2} within the elements, are positions first position=a 2nd position=a 3rd position=2 what I want to do is this: take a look at the first list, locate the lowest 3rd position and display that element. then since the 2rd element had the lowest 3rd position I also want to display the 2nd element in the next list too. I want to do this for all the lists in the LIST. ill explain again in different words for clarity. for each list I want to find the lowest 3rd position. then display the element with the lowest 3rd position and its corresponding element in the next list. this is the first output: {{b,b,-8},{b,b,7}} this would be the final result {{{b,b,-8},{b,b,7}},{{c,c,-7},{c,c,6}},{{d,d,7},{d,d,-9}}} thanks so much!
