Problem - positioning in actionscript

Hi all, I have bought a dynamic xml loaded menu from a flash stock website. I am having trouble spacing the buttons as its totally controlled in AS2. I emailed him and no reply yet, as this is urgent, im posting my problem on the forums, hopefully someone will help me.

The code is as follows:

// List of the buttons
var itemList = []


// The xml data
var xmlSource:XML = new XML

// Loading the xml
xmlSource.onLoad = function(success:Boolean):Void  {
    
    // When the load finishs...
    if (success) {
        
        // Settings
        xmlSettings = xmlSource.firstChild
        
        // The first node of the xml
        xmlRoot = xmlSource.childNodes[1]
        
        // The item nodes
        xmlItems = xmlRoot.childNodes
        
        // The total of items
        total = xmlItems.length
        
        // Creating the buttons
        for (i=0; i<total; i++){
    
            // Attachs thee buttos
            holder.attachMovie("button", "button" + i, i)
            // Inserts the button in the array
            itemList* = holder["button" + i]
            // Puts the text
            itemList*.txt.text = itemList*.txtColor.text = itemList*.ref.mcReflect.txt.text = itemList*.ref.mcReflect.txtColor.text = xmlItems*.attributes.name
            // Resizes the textbox
            itemList*.txt.autoSize = true
            // Centers the text
            itemList*.txt._y = itemList*.txtColor._y = -itemList*.txt._height/2
            // Resizes the color text
            itemList*.txtColor.autoSize = true
            //  Resizes the area
            itemList*.area._width = itemList*.txt._width
            // Resizes the mask
            itemList*.ref.mask._width = itemList*.area._width
            // Resizes the area
            itemList*.area._height = itemList*.ref.mask._height = itemList*.txt._height
            // Centers the area
            itemList*.area._y = itemList*.txt._y
            // Centers the area
            itemList*.area._x = itemList*.txt._x
            // Positionates the reflect
            itemList*.ref._y = 0
            // Hides the color
            itemList*.txtColor._alpha = 0
            // Sets the color
            itemList*.txtColor.textColor = itemList*.ref.mcReflect.txtColor.textColor = "0x"+xmlItems*.attributes.color
            // Resizes the reflection text
            itemList*.ref.mcReflect.txt.autoSize = true
            // Resizes the reflection text color
            itemList*.ref.mcReflect.txtColor.autoSize = true
            // Links
            itemList*.link = xmlItems*.attributes.link
            // Scale
            itemList*.maxScale = xmlSettings.childNodes[1].firstChild.nodeValue
            // Centered
            centered = xmlSettings.firstChild.firstChild.nodeValue
            // Menu Width
            menuWidth = holder._width
            // Starts centering the menu
            Start = true
    
        }

    }
    
}

// ignore white 
xmlSource.ignoreWhite = true;
// Loads the .xml file
xmlSource.load("source.xml");


holder.onEnterFrame=function(){
    
    // Centers the text
    if (centered){
        
        //holder._x += ((menuWidth -holder._width/2 + menuWidth) - holder._x)/3
        
    // Aligns to the left
    } else {
        
        holder._x += (0-holder._x)/3
        
    }
    
    // Starts centering
    if (Start){

        // Does this to all the buttons
        for (i=1; i<=total; i++){
        
            // Makes it button be below the other
            itemList*._x = itemList[i-1]._x + itemList[i-1]._width
        
        }
        
    }
    
}

I have played with the numbers in this part of the code and discovered that this is the section where it is controlling the spacing between each button

holder.onEnterFrame=function(){
    
    // Centers the text
    if (centered){
        
        //holder._x += ((menuWidth -holder._width/2 + menuWidth) - holder._x)/3
        
    // Aligns to the left
    } else {
        
        holder._x += (0-holder._x)/3
        
    }
    
    // Starts centering
    if (Start){

        // Does this to all the buttons
        for (i=1; i<=total; i++){
        
            // Makes it button be below the other
            itemList*._x = itemList[i-1]._x + itemList[i-1]._width
        
        }
        
    }
    
}

What I want to do is make the space between the buttons bigger.
