Change the 3 to 2. The error says it all. The list has 2 items not 3.

Your number of list is not 3 bro. First make 3 list for 3 integer index. If you will create the it will automatically load 3rd position of list.

I guess you don’t understand the concept of lists. I gave you the answer already.

it works perfectly for me. im sending a list of airtable data to another screen.

You are trying to get 3rd item of list, but your list has 2 elements. In first picture, click gear icon of blue list block and add another element, so you will able to add one more element to your list.

If you need only 2 item, then select 2nd item of list, instead of 3 in second screen’s blocks
