当我尝试运行我的代码时出现以下错误。

TypeError：错误＃1010：术语未定义且没有属性。

    private function calculateFIX001Value(custfields:Array):Number
    {
        var result:Number = new Number;
        var valueObj:Object;

        try{
                var markUp:Number = 0.01;
                var projectValue:String = "";
                var marketCategory:String = "";

                for each (var custField:Object in custfields)
                {
                    if (custField.fieldLabel == 'Segment Category')
                        marketCategory = custField.selectedValue[0];

                    if (custField.fieldLabel == 'Project Value (R)')
                        projectValue = custField.selectedValue[0].toString().replace("R","");
                        projectValue = projectValue.replace(",","");
                        projectValue = projectValue.replace(",","");
                        projectValue = projectValue.replace(",","");

        } catch(e:Error) {
            Alert.show(e.toString());
        }

        return result;
    }

TypeError: Error #1010 也称为“空指针异常”，这意味着您试图访问空对象属性。

如果您查看堆栈跟踪告诉您的行，您可能会发现原因没有太大问题。

这是帮助您解决问题的间接答案：（因为您的代码中有很多东西可能为空或未定义并导致此错误）

你几乎所有的代码都在 a 中try/catch，所以你的错误实际上并没有被抛出，你只是在追踪被捕获的错误。

抛出错误（通过删除 try/catch 或在 catch 块中手动抛出）：

catch(e:Error) {
    Alert.show(e.toString()); //instead of this, for debugging, do the line below:
    Throw e; //this will throw the error, so you will get your stack trace and the line number of error
}

要获取错误的行号并查看堆栈跟踪，您需要在调试播放器或您的 IDE（例如 Flash 或 FlashBuilder）中运行。
