Unable to generate a simple nested list

[Ro-Ra]

Hi! As a completely new Dynamo user I seem to be having a hard time generating a 2D-array of points that are present in many of the tutorials.

I.e. example from here:

Lesson 06 - Nested List Management

or here:
https://primer.dynamobim.org/02_Hello-Dynamo/2-6_the_quick_start_guide.html

The points instead are generated diagonally as a straight line. The list has 20 items rather than 400.

Right click the last node and set lacing to cross product.

Thanks it works!
