Hi carlitos,
here is a possible solution. In green nodes i added, or modified (i put "true" include headers parameter of Get Table Column node). I did not remove nodes that are useless. The result you wish is outputted by "Finished Processing" output of the green "Process list" node I added, ordered ascending from lower value to greater. Probably there's better ways to do this, I'd investigate "Process List" node.
regards
michele
EDIT: sorry i noticed now you wish not only occurrences but also values... should be not difficult to modify in that way
