button update sliders

[breadbox]

I'm looking to have a button in the UI update a slider.

I want the button to query the number of incoming points and set the slider to that value.

there is an hscript in the button but in not sure what the code should be? I can't figure out how to access the number of points in an object through the hscript and set the value for the slider.

I am trying to use: npoints(node_name)

which might be getting the value, but how would I set the slider to update once the button is clicked.

would be something like setAttr in maya? something with hou.node.parms?

Ideally it would reference itself so that if the node was duplicated it would instance without problem.

here is my test file

getMaxPoints - Copy.hipnc

In hscript, it would be something like this:

opparm . parm_name ( `npoints(opinputpath(".", 0))` )
