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?
