[Closed] Linking Patch constrains via scripted controller

Hi guys,

I have roughly 300 Objects with a path constraint assigned to them (not animated though). The objects are evenly distributed along the path. I now need to animated all those objects along the path. Since I dont want to edit 300 objects by hand, i thought i set up some sort of wiring between the percentage of the individual object and a dummy, that is following the same spline as my 300 objects.
However, the wire parameters won’t let me do something like this:

$Object1.pos.controller.percent + percent

It says there was an illegal self reference…
Is there a way to have one value (percentage of the dummy) drive another with respect to its initial value? something like this.percent += master.percent.

Any suggestions?
