Issue with driver script

posted to: Wheel on Path

Hi Wayne,


I'm using blender 3.3 and am having an issue with the driver script in this lesson. I have triple checked the expression I entered but I still get the error invalid python expression. I press play in the console and don't get any errors but when I update dependencies the error invalid python expression doesn't clear.


Any help will be appreciated.

Thanks,

Mark.

    Hi Mark hhobbsy_74 ,

    Could it be the discrepancy between 'diameter' in the Expression and 'dimensions' in the Variables name?
