How to use Code Block in List.Map ?
I am a new one in Dynamo.
This few days I am study about List, and List.Map is confusing me.
In the attatchment is the file about the question.
I want to add a number to all item in a List, and I use several way.
The builtin funformula, it works well.
The formula, it can only work for the first run time, and will not change for the next time when I change the formula.
When I use the code block, both I use the normal code block or self-define function, I can not get a result, they are all null.
I must have made some problems. Would you please help me to solve it, thank you very much.
