Vertical scrolling movieclip

Hi Guys!

I just graduated from college in graphic design and I am trying to make a flash portfolio page to showcase my work. I have everything done so far except that I am having problems with this one bit of actionscript…I have been at it for weeks, looking at diff. tutorials, but I just can’t seem to get it.

I have a movieclip (“strip”) and I want to it scroll up and down depending on where the mouse it, I also want it to duplicate so that it never stops scrolling…just keeps on looping. I am working this off of another tutorial that I found, but I am having trouble getting it acclimated to my flash.

If anyone can point out my error, or send in the direction of an EASY way to do this, I’d be extrememly grateful…i’m getting soooo frustrated. ARGH!

Here is my code

//initialize
onClipEvent(load){
percent_increment = .075;
addstrip2 = false;
}

onClipEvent(enterFrame){
this._y += (_root._ymouse - 10)*percent_increment;

if(this._y <=0 && this._y >= -this._height){
if(addstrip2==false){
this.duplicateMovieClip(“strip2”,1);
addstrip = true;
}
_root.strip2._y = this._y + this._height-1;
_root.strip2._x = this._x;
}
if(this._y <= -this._height){

	this._y = _root.strip2._y + this._height - 1;

}

if(this._y >0 && this._y < this._height){
if(addstrip2==false){
this.duplicateMovieClip(“strip2”,1);
addstrip = true;
}
_root.strip2._y = this._y - this._height + 1;
_root.strip2._x = this._x;
}
if(this._y >= this._height){
this._y = _root.strip2._y - this._height + 1;
}
}
