Thanks so much

Hey @Ammar_74

you opened up the very same thread already, please refrain from doing so in the future. We usually answer questions quite fast. I know you are working on an assignment with a due date but the forum is not the place where people should do your homework. Most of your problems could be solved by searching the forum or the https://hub.knime.com/ for example workflows etc.

Best regards
Lars

I’ve just see the other topic. You can delete this one as administrator if you pleased. Your answer in there was very similar to this one.
