Issues with moving objects with joystick

OS Win10
PsychoPy version 3

I am trying to create a motor task which uses a joystick to move a small circular image to different targets. I have managed to create the targets, circular image and got the joystick to move the small circular image in builder.

Although, the joystick only moves the circular image on a diagnonal trajectory from bottom left of screen to top right. This also seems to be inverted, so when I move the joystick up it goes down. Any ideas how I can get the image to move across the whole screen in response to the specific movements of the joystick. Thank you in advance.
