Running a Work Email Waterfall: Steps and LinkedIn Profile Search Tips

I need help running a "work email" waterfall for this table: https://app.clay.com/workspaces/48483/tables/t_aZtFzr7dbU3k/views/gv_xSZmrgyAPYwc I was able to run the first 10 rows, but now can't figure out how to run the remaining rows. Also need to make sure that i'm not wasting money paying credits for duplicate responses. can someone send step by step instructions for running this waterfall, then i need to search for LinkedIn profiles. It seems like Clay is getting too complicated.
