The code below works. I'll find out why the values are not passed to the callback function the way you have it and get back to you.

import viz
import vizmenu

viz.go()

class makeMenu:
	def __init__(self):
		
		#Menu Generation
		self.treadMenu=vizmenu.add()
		self.command=self.treadMenu.add("Commands")
		self.speed=self.treadMenu.add("Speed")
		
		#Command Box

		self.go=self.command.add(viz.BUTTON_LABEL,"GO")
		self.stop=self.command.add(viz.BUTTON_LABEL,"STOP")

		
		#Speed Box
		self.lspeed=self.speed.add(viz.TEXTBOX, "LEFT BELT SPEED:")
		self.rspeed=self.speed.add(viz.TEXTBOX, "RIGHT BELT SPEED:")
		

trMenu = makeMenu()

def moveBuffer():
	print 'Left Belt Speed:  ',trMenu.lspeed.get()
	print 'Right Belt Speed: ',trMenu.rspeed.get()

vizact.onbuttondown(trMenu.go, moveBuffer)
