change bar position

Hey there! I have a distance bar in my game with a script I copied from internet,At the moment is appear on the top of my screen and I would like it to be in the bottom!... I dont know much about scripts and dont know which part of the script I need to change to do so... This is the script im using:

// set GUI bar width and height in the Inspector var barWidth : float = 500; var barHeight : float = 25;

// drag a texture as the icon to move on the progress bar var progIcon : Texture;

// where to set the GUI element to private var barProgress : float;

// empty objects represent the start and end of a level var startPoint : Transform; var endPoint : Transform;

// current Player position var playerPos : Transform;

function Update(){ // get level distance by subtracting start and end var totalDist : float = endPoint.position.x - startPoint.position.x;

// get player distance from start in X axis only so slopes / height doesn't affect result var playerDist : float = playerPos.position.x - startPoint.position.x;

//turn the playerProgress percentage back into the scale of barWidth barProgress = playerProgress / 100 * barWidth;

}

function OnGUI() {
// create a GUI group the width of the bar and twice its height // in order to leave room for 'Start' and 'End' text under the bar GUI.BeginGroup (new Rect (10, 10, barWidth, barHeight*2));

//draw a box as the backing for the progress bar, blank text inside GUI.Box(Rect(0,1,barWidth,barHeight),"");

 // create a label to draw the progress icon texture, use barProgress var
 // to set its X position, 0 as the Y position and width and height of the texture used
 GUI.Label (Rect (barProgress, 1, progIcon.width, progIcon.height),
 progIcon);

GUI.EndGroup();

}

Thanx a lot!
