from your screenshot I can assume that you want to write the model directly into a csv file.
This is not possible, as the Write CSV operator excepts an example set , or data table.
What you can do is either, store the trained model in your RapidMiner repository (using the generic Store operator) or write the labeled data after applying the model to a csv file.

P.S.: To make it easier to get help and a fitting answer, it's helpful to formulate a concrete question and explain what you want to achieve and what you have already tried.
