Is it possible to get the variable made in my wrangle. And fed it to a channel of another node? i made a attribute integer and named it i@has_points. But when i add @has_points to the channel of a node it doesn't do anything.

Some variations - same node and other node. Red colored wrangle has the 3 example parameters.
