Hello,

use the list block "list from csv table" to get a list of rows, which you can loop through with a "for" statement.

You will need the File component to read the CSV file, the do as above.

If you are asking for help, I recommend you to make it as easy for others to be able to help you ...
You probably will get more feedback then...

which means in your case post a screenshot of your relevant blocks...

To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...
Thank you.
