    well, your blocks look a little bit strange...

    you have a complex list of lists, just use Do it to find out, how it looks like after each step of using lookup in pairs...

    It helps to follow the already provided links:

    • how to work with lists
    • how to work with list of lists (pdf) by appinventor.org
    • see also An example of a complex List of Lists

    In the example blocks below I looked for the first and displayed the value of tag aDate in Label1 like this

    you might want to loop through the different s using a for each in list loop....
