"Deleting missing values from a label"

I know this is probably a very simple thing to do but i haven't been having any luck with it recently. I have survey data and there are many missing values under each question. I am looking to create a decision tree and I have set a certain attribute as the label. This attribute only has 900 entries out of 3200. I only want to use the entries in the survey with a non missing value in this column. I would really appreciate any help with this.



never mind. . . i had left out a few values in the replace missing attributes operator. One of those stupid mistakes that took ages to notice.

    Hi,
    you can use the "filter examples" operator to select only examples with labels present.
    This does make more sense especially for the label attribute than replacing the value with some constant.
