Warning Icon

Because I just start using Appsheet, I want to ask a few question here. What’s the meaning in that column? Because I didn’t found any error when I test the App. And how can I find those warning icon?
Screenshot attached

Thanks

It most probably relates to Duplicate Key Fields in your data set. For instance I can see in your first screenshot that you have 2 records called IT Asset. If your Asset Category column is designated as your Key then you cannot have two records with the same Category Name…

The yellow triangle means the column is of type Ref but the column’s value does not reference a row in the target table. See also: References between tables
