bind puzzle not working

Here is my html file.

Thx, It works well now.
By the way, how to rotate an object in Z axis. I try that below but doesn’t work.

    var red_p = 0.47;
    var blue_p = 0.15;
    var i = 180 / Math.PI;
    var j = 360 / Math.PI;
    var red_anchor = i*red_p;
    var blue_anchor = j*red_p + i*blue_p;
    var white_anchor = i * (red_p + blue_p + 1);
    
    var object = app.scene.getObjectByName("pie");
    var anchor_red = app.scene.getObjectByName("center_red");
    var anchor_blue = app.scene.getObjectByName("center_blue");
    var anchor_white = app.scene.getObjectByName("center_white");
    var mat = object.material;
    var index1 = mat.nodeValueMap['red_percent'];
    var index2 = mat.nodeValueMap['blue_percent'];
    mat.nodeValue[index1] = red_p; // red part percent
    mat.nodeValue[index2] = blue_p; // red part percent
    anchor_red.rotateZ(red_anchor);
    anchor_blue.rotateZ(blue_anchor);
    anchor_white.rotateZ(white_anchor);
