Loading Attribute expression values

[CinnamonMetal]

How do you load the value/animated expression value into Python as an attribute ?

Is it possible to load parameters from a fit vop into vex/python and manipulate the parameter down the network ?

I'm trying to load a parameter from a fit vop node into a point wrangler but nothing is working ?

For example, I want to load `srcmin_v1` & `srcmax_v3` from the fit vop.

if(@Frame < 6){
@srcmin_v1 = -2.2;
}else
@srcmax_v3 = 0.6;
