Hi David! Thank you too for your helping! I like the idea of having a helper to convert to strings, thats great! Also, I didn't know about flatten, thats really interesting! Basically my problem description was only the endpoint of what I wanted to archieve. I'm using Racket right now happily to search through a sqlite database for personal learning. For this I'm using query-rows from db. This returns a list of vectors. At first I printed the results with a function that takes the vectors and transformed them into a human readable information, because I knowed how to iterate over a list, transform vectors and how to use the repl. With your, and the other David's (sorry, could not resist!) help I'm able to put that onto a webapp what I will try next - after I managed to memorize und truly understanding that concepts. With those naive approach (playing with data) I'm learning quite good how all fits together. You two really helped me to understand how it's meant to be used! Thank you!
