Hello,

The valueName property is set the name that will be used to store the question value. If it isn't set the question name is used as the value name. You can for example create two different questions with different names but with the same question value. In this case these two question will be modified synchronously.

You can read the documentation - https://surveyjs.io/Documentation/Library?id=Question#valueName

Thanks, Serge

        You can have an expression equal to a question: {questionValueName}. However, the main goal of this function is to share data between several questions.
        Here is the example.
