Desperate... cant get these next and previous buttons to work with xml menu

Maybe im double posting from the xml menu thread, but im soooooooooo stuck its making me crazy…

Using the Xml_Menu_v2_buttonDown that hga77 created, ive been trying to add a next and previous button to it with no success.

I can sort of get the buttons to move between the sub levels but, cant get actions to execute and move to the next or previous parent nodes.

_parent.next_btn.onRelease = function()
	{
		trace(current);
		if (curItem != item)
		{
		currentbtn = parseInt(previousSub._name)+1;
		executeAction(action,previousSub);
		trace(current)
		}		
	}

Its doing my head in… Ive spent the last 3 days looking at this and i cant let it go… Please put me out of my misery…
