@elsamuel especially with new people on the KNIME forum I think it would be best to ask questions and point to helpful resources about how to write a good forum question and how to share data (How to write a good post) or provide a logfile if necessary (Files Corrupted During File Transfer - #8 by mlauber71).
I know that as an experienced user it can be frustrating to see just screenshots (again) but sometimes it is not easy to decide if a problem can be solved by a quick question (that is screenshot) or it might need a more complex example (that is data and a sample workflow). In my experience often the process of providing such workflows and sample data might lead to some thoughts about the task (business problem) itself which often is at the heart of a seemingly ‘technical’ problem. As (if I might) elders 
in this forum we could set ourselves the tasks of guidance and help to broaden the overall understanding of KNIME (more often than not including my own).
Thank you for all your valuable work and help you are providing for the KNIME community.
