I really have a hard time with everything in Tableau, because what I see with videos and what I see in the software are not related at all there is a missing part in each and every video of Tableau, I can not follow up I have only been watching the videos with no practice
I apologize for any discrepancies.
One of the main reasons for this is that Tableau introduce a new version of the software every few months. And hence there are some differences.
Feel free to contact me via email if you encounter additional difficulties after the one we resolved yesterday.
