Can anyone help me with the meaning of this error I get when I click on a fifth down tab in thunkable mobile preview? That’s a link to a screen shot of the error ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/7/079d0612ae8726380e282c03c3864b05aba738a2.jpeg) ---

Do you have component/blocks on that screen? ---

No. There are other screens with no blocks but works fine. It’s just that screen. I have added a list on that page. I don’t know if that’s the problem ---

The first error says you have an **Array** which is a **List** with wrong or **null** reference. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/e/9eb05145b9bb6673196cf3596165084e0974180f.png) ---

I am trying to build a settings page so I used the list view to list the items like my profile, notifications etc. But I have not told the list what to do. Is that the problem? ---
