Player control action script

I have this action script applied to a slider menu button that controls the movie clips reverse, play, pause, etc… functions. I am making a custom flash movie player in flash where I can import videos into cool skins that I have created. Well anyway my question is the slider menu will only work when its aligned to the left side of my canvas, and stops working when I place the menu controller in the center of my movie. Im guessing somewhere in this action script needs tweaking in order to move the menu controls off the left side of my workspace. I want it centered!!! :frowning: :frowning: :frowning: , what numbers in this code or what extra code do I need to edit to move the slider around to wherever I please.

heres is what the code looks like:

stop();
onEnterFrame = nextFrame;
myButton.onEnterFrame = function() {
this._x = _currentframe + 25;
};
myButton.onPress = function() {
delete this.onEnterFrame;
startDrag(this, false, 25, this._y, 125, this._y);
onEnterFrame = function () {
gotoAndStop(Math.round(myButton._x - 25));
};
};
myButton.onRelease = myButton.onReleaseOutside = function () {
stopDrag();
onEnterFrame = nextFrame;
this.onEnterFrame = function() {
this._x = _currentframe + 25;
};
};
