Problems adding an instance within another instance.

Hey guys, I'm trying to create a table where you can add additional rows but also add a button underneath to add a whole new table which in turn can also have it's own rows added. The table part works fine, my problem occurs when there is more than one table and I add a row to the last one it adds itself to the first table, regardless of my clicking the button located in the last table. I'm guessign that I'm not referencing it's parent correctly. I'm fairly new to livecycle and it's thrown me for a loop.

Thanks
