Hello everyone,

I am trying to get the number of points in a group with the pointlist fuction, but having it erroring.
If you can help me out it would be much appreciated.

Thanks
Francesco

hi, if you read the error message you see that that function is undefined, which means it doesn't exist.
That's because it's an expression function (hscript) and you are trying to use it in a vex context.

You should use vex functions in a vex wrangle.
In your case this one should suit for your needs
