Using Set Value in Relations

Hi,

I'm trying to set a value on a divide a/b box. I have incoming animation
connection on 'a' but i want to 'hard' set the value on 'b' (as you would by rt
- click > set value in the GUI).

This is as far as i've got:

lDivideBoxZ = lConstraintRelation.CreateFunctionBox( 'Number', 'Divide (a/b)' )
lDivideBoxValueZ  = FindAnimationNode( lDivideBoxZ.AnimationNodeInGet(), 'b' )

I tried casting an integer and using fbconnect to connect lDivideBoxValueZ  and
the integer but it didn't work.

Any help appreciated, this is the only missing piece of my scripted relations
tool.

Thanks
