Two hours later and I finally figured it out, lol. Came across this tutorial: http://www.rbtwhiz.com/rbtwhiz_deltaInjection.html

 What I was missing was:

  valueOpDeltaAdd
                               // The controlling figure
                              Figure 1
                               // The controlling group
                              head:1
                               // The controlling channel
                              PBMCC_01
               // The control multiplier
               deltaAddDelta 1.000000

 

All is well now. :D 3 replies to my own topic? LOSER!
