What I'm trying to achieve is a staircase that grows 10 centimeters with each iteration. However, as far as I know, geometry nodes only has Scales operations for increasing the size of geometry, which, as you can see in the image, results in it getting larger than 10 centimeters.

Additionally, each time I try to connect anything to the scale vector, the scaling stops completely in every iteration. I don't know if I'm doing something wrong, if this is impossible to be done, or if I'm just missing something.

Can you tell me if there's a way to achieve this? By the way, for the problem, I only showed the outer walls of the staircase, but if there's a solution for the walls, I'm sure it will work for the steps as well.

You do not have to scale, create new cylinders with growing radii by adding to them. The vertical stacking you can achieve by adding offset to a newly created ring. The Merge by Distance I would put outside of the Repeat Zone, because it does not make sense to repeat this action on each step, once at the end is enough.
