Sorry for the simple question but it does not make sense to me. I have a Main List and a SubList. Independently they both display fine. When I insert the SubList at the end of MainList and then display the SubList content comes out as a single line. What am I doing wrong? Thanks https://x.thunkable.com/copy/8476921a12ae8ccb64ac76f11020011e
You created the list {1,2,3} and then told Thunkable to add the list {101,102,103} to the end of that list. So it did and you got {1,2,3,{101,102,103}} which is an embedded list and tricky to work with. The fourth item of that combined list is a list itself.
What you wanted, I assume, is {1,2,3,101,102,103}.
For that, you would need to loop through each item in the sub list and add that item to the end of the main list.
Or, if you prefer not to use a loop, convert each string to text, join them (with a “,”) and then convert back to a list. For that, you would use the Make List from Text block: Lists Blocks - Thunkable Docs
