Hi All please see attached. can anyone tell me why $MYSCALE should be listed as undeclared variable . the attribute “myscale” value for the attribute should 1.0 . Yet using point() $MYSCALE throws an error in H14. ?

It seems that field doesn't accept point attribute variables. When you enter $ to get a preview list of the valid variables it only lists global ones such as $F, $T etc.

This seems pretty logical since the mountain SOP runs over the entire geometry and not over each point separately like a wrangle or attribVOP.
