Message: '$IG.ControlObjectProps.Count' is null or not an object

Message: Sys.ArgumentUndefinedException: Value cannot be undefined.Parameter name: baseType

Particularly on the line

$IG.LayoutPaneProps = new function()
{
var count = $IG.ControlObjectProps.Count;
this.ScrollLeft = [count++, 0];
this.ScrollTop = [count++, 0];
this.ScrollBars = [count++, 1];
this.Count = count;
};
/******************************************END LayoutPaneProps ENUM********************************/

$IG.ContentPaneProps = new function()
{

this.ContentUrl = [count++, ''];
