Multiple Data Viewer Lists/ screens

Hello again!
I need some help with this: I have 2 screens, each one with 2 data viewer lists. Then I have a
Solution Screen where I want to show the data about each item.
again struggling with the blocks to use and the variables…
How do say to the Solution Screen which item/DataLlst was clicked? and access the correct DataTable?
Sorry, maybe I’m asking too much, but wanted so much that works.
Thanks in advance!
