How to controll a motiontween in timeline with startdrag on a slider?

[Cyper]

Do someone know how I should do if I want to control a motiontween (zoomeffect) in the timeline with a slider, like a soundslider with startdrag but it should controll the motiontween instead.

Zoom out when sliding left and zooming in with sliding right depending of what position I have drag the slider in.

Any ideas or tutorials?

Thanks,
