OOPS! That didn't quite hit the mark
I am new to using RapidMiner and am trying to use the packaged tutorials. Starting with tutorial #1, I can drag and drop the Retrieve Deals ok, but when the next frame instructs me to drop in the Decision Tree operator I continually get the OOPS! That didn't quite hit the mark balloon no matter where I drag the operator to. Am I missing something in the instructions? I have had the same problem in the other tutorials I have tried. Suggestions?
