Coupled variables in Tkinter???

[Maurice]

Dear all,

I want implement a GUI in which I've four sliders using Tkinter.
To do this I've put all the stuff in a class:



class SliderAndAxesWidget:
	def __init__(self,master):

		self.Slider1Value=IntVar()
	 	self.Slider2Value=IntVar()
		self.Slider3Value=IntVar()
		self.Slider4Value=IntVar()
		
		self.Slider1Value=0
		self.Slider2Value=0
		self.Slider3Value=0
		self.Slider4Value=0
		
		self.sliderLabel=Label(frame,text="Positions")
		
	 
self.xCFP=Scale(frame,to="255",orient="horizontal",variable=self.Slider1Value,command=self.say_test)
	 
self.yCFP=Scale(frame,to="255",orient="horizontal",variable=self.Slider2Value,command=self.say_test)
	 
self.xRcv=Scale(frame,to="255",orient="horizontal",variable=self.Slider3Value,command=self.say_test)
	 
self.yRcv=Scale(frame,to="255",orient="horizontal",variable=self.Slider4Value,command=self.say_test)
		
		self.xCFP.grid(column="0",row="1")
		self.yCFP.grid(column="0",row="2")
		self.xRcv.grid(column="0",row="3")
		self.yRcv.grid(column="0",row="4")
		self.q=Button(frame,text="GoodBye",command="exit")
		self.u=Button(frame,text="Update Axes",command="self.UpdateAxes()")
		
		self.q.grid()
		self.u.grid(column="1",row="5",columnspan="2")
		
		frame.grid()
		
		def say_test(self,master):
		print self.xCFP.get()



This class I use in a pyhton program as follows:
	

	root=Tk()

	app=SliderAndAxesWidget(root)


	root.mainloop()




My problem is that when I used on of the four sliders, the other three 
also change so they are coupled.
I didn't expect this because the have different variables.
How can I prevent this coupling??

Thanks in advance.
