how to preprocess data for classification in weka

I am starting to use WEKA and I want to use the k-NN classifier on this dataset I am able to import the dataset into weka. But when i want to start the classifier, there it does not show me any information about how much instances where correctly classified and how much not. I want to classify according to the status column. I guess i have to do some sort of preprocessing here because the status attribute is interpreted as a numerical value. ?! Can anybody explain what sorts of preprocessing i have to do for this kind of dataset?

The easiest thing to do is probably to replace the numerical values in the status column with strings so that Weka recognises that they are categorical values.
