No value is inserted at level6.
When a new value is received it will be overwritten.
I take 2 and store it in level6 and when I get a new value 3
Then I want to make a list [2,3].
By the way, the existing value disappears and level6 becomes 3.
Normally, when a block is constructed as shown in the figure, the values are accumulated.
Why aren’t the values accumulating?
What is the solution?
