Move canvas mouse with WorldViz wand

In the vizard demo launcher, there is a menu that can be interacted with by pointing the wand at it to move the mouse. So far I have the canvas set up, and I have set the canvas mouse style to CANVAS_MOUSE_VISIBLE, but I am somewhat lost on the rest. Here is the function I have come up with:

Code:
def manualCursorPositionTask():
	global listDisplayed, grabber
	
	while True:
		if listDisplayed:
			pos = grabber.getPosition()
			x = pos[0],y=pos[1],z=pos[2] 
			euler = grabber.getEuler()
			intersection = viz.intersect([x + math.sin(euler.yaw/180*math.pi),y,z + math.sin(euler.pitch/180*math.pi)], [x + 100*math.sin(euler.yaw/180*math.pi),y,z + 100*math.sin(euler.pitch)/180*math.pi])
			
			if intersection.object.id == canvas.id:
				canvas.setCursorPosition(intersection.point, viz.CANVAS_CURSOR_PIXELS)

		yield viztask.waitFrame(1)
This is based off of example code I found in example code, specifically canvasExample.py. This code does not seem to work, however. I have used viz.director() to add the function to Vizard's task management as well. If anyone could explain to me what I would need to do to interact with a menu by pointing the wand, or what's wrong with my methodology, I could really use an explanation. Thanks.
