New KNIME user here so apologies in advanced for what is probably a very simple new user problem.
I am trying to feed part of the Titanic data set into the decision tree node, but I get the error in the subject line above. Trying to use the random forest node gets me a similar error: "No possible target in input (node not connected?) -- unable to configure."
I've reduced the data set to just numeric values, converting sex and port of embarkation to ints and imputing the missing age values. I know I need to specify 'Survived' as the target but cannot open the configuration dialogs to do so.
