Dragging mc with call back to nextFrame and prevFrame

I have some what completed the scripting on this animation. I can’t seem to get the mouse to let go of the object when released from dragging. It still seems to not give any attention to the line of script that tells it to stop dragging on release. Do you have any ideas? I have attached the fla. to this email. I thank you for any help you can give me — jas_G.

P.S. to give you a little insight I am trying produce a drag slider that calls back the next frame or previous frame of the dragged movie clip. When done it wil control the volume with the effect of a real volume slider, since it changes orientation from one end to the other.

I have used an xmouse feed back, but it does not seem to respond to mouse commands. What to do???

I Have attached current fla. below.
