Extrusion Expression + Test Render + Problem

subCurve2.maxValue = Main_Ctrl.translateX/110;


subCurve2.minValue = Main_Ctrl.translateY/10.1;

So, I have extruded a polygon using curves and I want it to extrude along the line. I have to use the minValue and maxValue.

My First Test Render

Currently, it seems my expressions went out of hand. So, I have to use "Set Driven Keys" for Extrusions.
