Use structure data in Sequencer

Need to loop a sequence changing parameters such as sun position or camera effects at every loop.
I’ve setup a csv file with a couple of them for a test and imported into a structure.
Now I’m struggling to understand how to a) import a parameter from the structure in sequencer b) use them in sequencer.
Right now I used this BP mixing various tutorials without any real understanding of what I’m doing

resulting in the ability to see them in the sequencer, but without any of the data value

I didn’t find any documentation of the Break SeqParam node. Can anyone suggest a way to at least achieve point a)
