Hi,guys.

in the new popnetwork,I want to get the varable “$NPT” from the source object into the impulse count(as in the screen shot),but it doesn't work at all,but in the old popnetwork,it is working,I don't know why.could you help me?Thank you very much!

On the Source tab switch to “All Points” then the Impulse Count will grey out because the source will be fetching the number of points from the input instead. This is the equivalent of $NPT or @numpt. So make sure your input source is providing only points. You can insure this by dropping down an Add node an activating delete all geometry but keep all points.

Thank you for your answer.I Will try it.
