Hi,
solution is very simple.
Just right-click on the border of the sequence and select "Add Sequence Local" from pop-up menu. The yellow node will appear near the border. Now you can wire some data to this node and read these data from this node on any of later frames.
Another convenient idea is to use local variables to pass data from one frame to another. But this is good only for small amounts of data.
Good luck.
