Interesting…can you try moving those blocks to a button click event rather than the screen opens event? ---

Oddly enough I tried swapping to what you had in your screenshot and it still works fine? ![Screenshot 2021-05-18 at 17.25.18](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/5/e533fd4909e35e2c52480b3d6997b2aae5763216.png) I wonder if it’s an issue with multiple sheets? Can you try with just P1 and see if that works? ---

I created a new sheet with only one table and new project but I got the same result. The data viewer shows the values but the list viewer does **NOT**. ---

In both the button click and the screen opens events? ---

I changed the table name to P1P1 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/d/8daebae3f009b9cd1f07c67ee3b923afa1afd30a.png) See the outcome ![Screenshot_20210518_194200_com.thunkable.live](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/d/5d4446d11ffbb2b2148d15634b2440c7f0682d2f.jpeg) ---

@domhnallohanlon I made another test. I like to test every possibility and thought is it connected to a pattern such as a letter followed by a number (P1) and will work if it is different? So I changed the table name to **PR** instead of **P1**. Guess what, it works fine. Can you confirm from your side? Create a sheet with one letter followed by 1 or 2 numbers and test if the `list of values` works. ---

🤔 so, when I change the name of my sheet I can’t sync with the data source… ---

You will need to delete it and create the data source again. You will have to bind it again with the data viewer and reconnect the code (You will not be able to view the **code** screen from first attempt) but this is hardly an issue. [Edit] You have to delete existing source from the My Data Sources tab. It will not work if you delete it from the project. ---

I now have a sheet called `pi` and a sheet called `k9` with identical data, but sorted in a different way. The alphanumeric sheet names aren’t working 😢 ![Screenshot 2021-05-18 at 17.58.55](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/6/064ebe38c466b99865c17bfacc617edb913a6a3a.png) For the time being can you switch to a different naming system? ---

> [@domhnallohanlon](#): > > For the time being can you switch to a different naming system? @bnice - are you ok working with slightly different table names for now? We’re looking into this at the moment and I can let you know more if I find out any more about the root cause. Thanks. ---

Yes, I already renamed my sheets. The names of my sheets are flexible. My sheets were named after Chromebooks, so I just added the brand name to the beginning of them and everything is working great at the moment. (Ex. ‘N22’ went to ‘Lenovo N22’) Thank you for looking into this. Hope we can find a solution! ---
