Accessing Global detail attributes through Python

[atron]

hi there,

I have a global attribute that i've made in a python node:

citySearcherDistanceTrav = geo.addAttrib(hou.attribType.Global, 'citySearcherDistanceTrav', '')

i've then set the attribute with some floats 

totalDistance = self.stepSize * hou.frame() #speed * time = distance travelled
        dt = str(totalDistance)
        geo.setGlobalAttribValue('citySearcherDistanceTrav',dt) #see image 1

But i can't seem to access the values in the next node directly below. 

I tried find global attrib not sure how to access the data in a python node again.

The Copy node throws away attributes by default. Go to the Attributes tab of the Copy and add your attribute name to the list for downstream forwarding.

Hi Atom, 

 

I can only see copy local variables which is checked. And then the standard topoint,toprimitive,to vertex , set ,mult, add and subtract table. 

What list do i add the variable to.
