Clip Plane Slider Position

[dobey]

Cant seem to get this right tonight. I am trying to echo the position of my clip plane slider and nothing I try is working. I have this:

Sub Main

/echo ${Window[OptionsDisplayPage].Child[ODP_ClipPlaneSlider].HScrollPct}

/end

If I use HScrollMax (should give me the scroll range if I am reading it right) I get 100 but Pct and Pos return 0 no matter what position I have the slider in. Any help would be awsome please.

Forgot to add if I use:

/notify OptionsDisplayPage ODP_ClipPlaneSlider newvalue 0

The bars range is 0 to 20 for min and maximum range.
