I'm trying to get rows from an excel table and add relevant rows to different files saved on SharePoint. I've got most steps working but 'Add a row into table' doesn't seem to be functioning as I expect, or as any tutorials show.

I'm expecting to see a list of columns where I can assign data from 'Get a row' - but I don't see this. There are no options when I click on 'add new parameter' either. I don't get anything from 'Get a row' from dynamic content, it's not even listed - is there something I can add in manually? I just don't know what I need to add in.
TIA
