Illustrator ScriptUI嵌套对话框按钮无法正常运行

如何解决Illustrator ScriptUI嵌套对话框按钮无法正常运行

嗨，我不是程序员，并且对javascript的了解很少，我想为Adobe illustrator的嵌套对话框创建脚本UI。有人可以告诉我我的这段代码出了什么问题吗？这段代码的作用是制作一个弹出对话框或窗口，当您按下按钮时，将关闭上一个对话框，并弹出另一个对话框，并可以随时关闭。期待指导我使其运行，感谢您的帮助

var ph = createLayer();

alert( test);

function createLayer()

    tier.alignChildren = "left";
    var c1 = tier.add ("checkBox",undefined,"W1");

    var c3 = tier.add ("checkBox","S1");

    c1.value = false;
    var tierButtonGroup = tier.add ("group");
    tierButtonGroup.orientation = "row";
    tierBtnOK = tierButtonGroup.add('button','OK');
    tierBtnCancel = tierButtonGroup.add('button','Cancel'),tierBtnOK.onClick = function()
    {
        tier.close(1)
    };
