Hi, I have struggling for a few days with the app inventor. I have created a simple games and I wanted to store the top 5 score, if the users score a high score which overwrite one of the 5 high score I should replace update the top 5 score. The above is the blocks regarding the storing and updating of top 5 score, I don't know what is doesn't work as I expect. Could anyone give a help please I would appreciate it.

Welcome,
When you add new score to list, you always need to sort them, and store the top five. This is what the strategy you need to follow.
That AppendValueToList block looks wrong.
If the value under tag scorelist is a simple list of scores, why would you want to add a single element consisting of the entire scorelist to it?
Isn't that what the append block does?
AppendValueToList( tag , itemToAdd )
Append a value to the end of a list atomically. If two devices use this function simultaneously, both will be appended and no data lost.
I'm so sorry I'm a really beginner to the app inventor, I have changed it to this. And the sort procedure for testing purpose I just do for index 4 and index 5 and what the result is instead of updating the new high score to index 4 and set the old lower score to index 5, it updates both index 4 and index 5 to the latest high score.
