In houdini 16 i wanted to scale particle according to age using this expression fit01($AGE,.2,.9)in a point node, it worked fine.
then with the same scene in houdini 15 i use exactly the same expression and its not working at all, even a simple expression like $AGE doesn't work, i think i've missed somthing in the syntax,
please anybody help

in my scene the point node issue is in the geo1 node in root tree
thanks
