Problems with Mass Addition

I have a list of curves which I put through the Length (len) command.

I want to sum the lengths of all curves in the list.

Mass Addition is giving me 2 values instead of 1.

I'm posting a screenshot of the error I'm getting on using it.

You are giving two branches, so it gives you two values, each on his branch. Each branch contains a list, then the total sum within each list is executed.
The lists are a collection of items such as a car carrying several people. The branches can be like lanes of a road, if you use branches then then cars (lists) are in different lanes and operate individually. If you want everything to come together on a rail, or in the same branch, right click on the input and active Flatten.
