to use cross valiation you need to have an example set as input. Right now you have a collection of example sets. You have different options how to handle this. I would suggest to use the "Loop Collection" Operator to loop through your collection of Example sets. Inside the Loop collection Operator your "Cross Validation" Operator would sit.
