When I try to fill the first element of list LDNCsv it simply won’t. Debug immediately after verifies the list is still empty.
I tried reducing the characters in the name of the list, and reducing the overall program size. Neither helped.

What happens if you replace `app variable C4` and `LDNCphone` with static text strings?
What happens if you create a very simple event such as `When button click` → `in list app variable LDNCsv set # 1 as "test"`? It helps to isolate that section and see if there’s something else causing it to fail.
Is there anywhere else in your blocks where you’re setting `app variable LDNCsv` to anything other than a list (empty or otherwise)?
What happens if you use the blocks in the screenshot above but remove the `set stored variable LDNCsv to` block?

I think you are onto something here. My APK was blowing up since my storage variables were null. So I moved a blank to them to keep them happy. But then I moved the storage to the app variable list. That must have confused it? How do I keep the storage variables happy when they are supposed to be empty? Put in a header? IDK. I replaced the variables with a number for the index, and a literal for the input and it still wouldn’t accept it.

Did you try this?

If so, can you share a screenshot of those blocks?
Stored variables need to be checked when the screen opens. If they are null, then set them to an initial value (`empty list` for lists, “” for text, 0 for numbers, etc.).
