Conveyor not responding to Analog speed

I try to control the conveyor speed with the Analog setting where I have a Potmeter (input=0-10v) and a digital display (output=showing the Potmeter value)

The display works prefectly, but the Potmeter when adjusted it just goes to max speed which is 10 and when going between 0.1 to 10 it’s only max speed that FactoryIO reads on conveyor.

How does your code look? How did you make the connection between the conveyor and the potentiometer?
