did you try it with autolayout? -> in my project this works

pressing loop on monad twice updates the stethoscope value...

wow, that was quick ;). unfortunately...it doesn't help. Here is my setup "inside":  so the stethoscopy node shows no value. outside:  it does not update :(

to be honest - i am bloody sverchok beginner - maybe i have to check some checkbox somewhere!?

ok, thank you for the information!

is it just supposed to work only in Blender 2.93? the custom attribute functionality is so great - is it possible to upgrade this to newer Blender versions? would be...

me too, but with Blender 3.3 error message:

i have the same problem with Blender 3.3 alpha. error is this (on a Mac):
