The green “rows” block is an _object_. And I believe it’s a list of objects, actually. I haven’t worked with it all that much but I think you’ll find this post and this whole topic useful: > [@\[Solved\] How to display rows from a table in thunkable x](https://community.thunkable.com/t/solved-how-to-display-rows-from-a-table-in-thunkable-x/492845/6): > > k. looks like you need a list viewer. and to throw all rows though a loop. see my screenshot below. first i put all rows into a variable. i send that variable to be filtered. i flter based on certain properties. think about a property as a column position in a given row. when you put ‘all rows’ into the loop, the loop looks at the entire thing 1 row at a time. then when you say look at property X, you are really talking about column X in the current row that the loop is looking at, starting wi… One other thing to note is that when you stack blocks that take some time to run such as “delete all rows” or “update value”, the blocks run in parallel. So even though it looks like the blocks you have will delete all rows and _then_ update a value, in reality they will attempt to run at almost the exact same time. To ensure that the update happens _after_ the rows are deleted, put the “update value” block inside the “delete all rows” block’s “do” section. That block should really say “then do” but it just says “do”. --- _[View the full topic](https://community.thunkable.com/t/very-slow-response-with-airtable/1224511)._
