function create_item_bg( h:Number, item_no:Number )
var fm_rect:Shape = new Shape();
fm_rect.graphics.beginFill(0xFFFFFF, 1); // ITEM BACKGROUND COLOR
fm_rect.graphics.drawRoundRect(0, 0, item_width, h + item_padding * 2, 0);
fm_rect.graphics.endFill();
return fm_rect;
function create_item_desc( item_desc:String )
var fm_text = new TextField();
fm_text.x = item_padding;
fm_text.y = item_padding;
fm_text.width = item_width - item_padding * 2;
fm_text.styleSheet = flashmo_style;
fm_text.htmlText = item_desc;
fm_text.multiline = true;
fm_text.wordWrap = true;
fm_text.selectable = true;
fm_text.autoSize = TextFieldAutoSize.LEFT;
return fm_text;
flashmo_sb.alpha=1;

Answer 1

function push_array(e:Event):void
    flashmo_item_list = [];
flashmo_xml = XML(e.target.data);
total = flashmo_xml.item.length();
for( i = 0; i < total; i++ )
  flashmo_item_list.push( { content: flashmo_xml.item[i].content.toString() } );
load_css();
that will reset your array.
