Hi! So, here’s the deal. I’m making a translation app and have a function where users can add lines of text to a list, then view that list on a separate screen. I’m trying to add another function where a user can tap an item on that list that they added which then grabs that text and tosses it back through the translator. My question is, how do I write the code that copies text from a single item in a list? I can handle the other bits. As for the bug, I can’t get the list viewer to show up on my mobile (iPhone 8+), but it shows up fine on the computer simulated thunkable phone. Is there a fix for this? Please let me know. Thanks! (Keep in mind the list can change at any time because it is user controlled – it can be cleared or added to indefinitely.) ---

Many thanks, this works out. Any clue on the list viewer not showing on mobile, or is that likely a my-end problem? I’m using the thunkable live test app on my phone. ---

I’ve seen issues where the live viewer will do stuff that a phone won’t. It’s unusual though. Can you post a screenshot of the blocks you use to populate your list viewer? ---

On my computer only, this screen functions as intended. On both my phone and on my peers’ computers, the My Phrases screen causes the app to go full-white and freeze. I think this error may have something to do with the stored variable, though I’m unsure. The previous bug simply wouldn’t display the list viewer, but now I need to solve this first. If you would like me to include a share link, please let me know. Thanks very much! ---

Do you have this variable set as an empty list? You can’t initialize a stored variable as such. So I wonder, did you let the variable know it needed to behave like a list This could be accomplished with a simple logic statement on screen open. If var = null set as empty list else do nothing ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/b/fbe22e54b27218bfb2259a735f038e5d15aaf76d.jpeg) ---

That was it. You’re a lifesaver. Thank you! ---

Would you be as kind as marking my post as the solution? 🙂 ---
