Thank you for the clearing that up.

I have several curves which I resample and turn on Curve U Attr and I like to group the points which are @curveu == 0. But in the group node if I toggle Expression on at the Base Group field only one point shows active. Expanding the String Value shows 1 and not all the points which are @curveu == 0.
If I visualize the curveu attr than I should get point ids like 0 27 54 81 108 135 162 189 …

Added hip file.

Thanks for the help.
