I cant seem to make simple transform values to control rig in blueprint

I spent today looking for an answer but to no avail,
I want to simply change the position of the leg from the control rig when Im pressing a button

Here is what i did

  • Use original premade asset control rig
  • add IA for my leg that i want to move
  • adding pre initialize control rig with “add mapped skeletal mesh” as seen here
  • Add a control rig component and child it to my “character mesh”
  • creating the following flow, attached an image.

what am i missing?
