Having some trouble editing the tech tree

[SpiralOut]

I'm looking at Community Tech Tree as a reference, but for some reason I can't get my .cfg file to edit any of the tech tree nodes. This is the syntax I'm using:

@RDNode:HAS[#id[start]]
{
  // -2568,1199,-1
  @pos = -2568,1142.3,-1
  @description = Is this thing working?
}

But the Start node in the tech tree remains unmoved and the description doesn't change. I've also tried adding :Final to the end of the first line with no luck. Also tried @RDNode[start].

I did successfully edit a PART module in the same .cfg, so I know it's getting loaded and that Module Manager is working. Any ideas what could be going wrong?

EDIT: I found the solution! I had to wrap the whole thing with a TechTree edit. This made it work:

@TechTree {

  @RDNode:HAS[#id[start]]
  {
    // -2568,1199,-1
    @pos = -2568,1142.3,-1
    @description = Is this thing working?
  }

}
