Oh great, houdini as so much ways to do things, glad you find one !
With my file you can see another one!
Have a good day

I also thought of forloop, but I don't know how to use it.
I can learn forloop from your file again!
Have a great day too!

Hey,

You can't access an attribute outside a wrangle by just typing @attribute, with few exceptions (like group expression...).
It should be a little vex expression to access to point, detail, vertex or primitive attribute, for example in your case : point(0,0,"exit_div",0) * 10.

If you want a deeper understanding of this, this is the template for this expression that you can find in the doc : point(surface_node, point_number, attribute, index)

It's "0" for the surface node because your attribute is set on the node you edit, but if you want to access an attribute outside, you can replace "0" by an absolute, or relative path like this : point("../attributepromote1",0,"exit_div",0) * 10.

Hope it will help you!
Have a nice day.

Thanks for your help, it's a bit hard for me, I'll look into it.
I tried to write in this way, and it did solve the error, but the Divisions are still the same result.

However, the problem is solved from another angle. There is a Divisions Scale option in PolyExtrude -> Local Control.



Before PolyExtrude, associate exit with divsscale through an expression, thus achieving the desired effect.
Thank you so much for your help and inspiration!
