[Closed] Ik elbow ctrl / help

Hello every one.

I’m nearing the end of a script that builds and rigs an IK/FK arm but I’m stuck on this part part, the IK elbow ctrl.

I’ve tried wiring the swivel angle of the IK Chain to the pos of the ctrl but I can’t get it to work. I would really just like to be able to “pick target” the elbowCrtl but I cant seem to find it in the max script help files. Could some one please point me in the right direction.

Thanks
