Vm167 analog inputs influence each other

Hi

I have connected 3 potis with 5k ohm to the vm167. Power source is the onboard 5V pin and as ground I use one of the GND pins.
When I change the position of one poti the shown values of the ohter analog inputs also change. What could I do to stop the influence of the analog inputs. (so far I have used the demo application)

Thanks for your help

[quote]What could I do to stop the influence of the analog inputs.[/quote]The influence may be lower if you connect the potentiometers to channels 1, 3 and 5.
And connect channels 2 and 4 to GND.
