Reading Javascript function returned value after execScript()

I want to be able to obtain the returned value of a Javascript function executed at an HTML page. Currently if I do 
execScript("alert(getUserId())","JScript")
I can see the right value in the alert box. I need to obtain that value to populate a field in my toolbar. How can I obtained the returned value of getUserId()? Let's say that I want to store it in a variable named "userID", then I am executing 
var userID = HTMLDocument.parentWindow.execScript("getUserId()","JScript")
but userID is null.

Hello,

According to http://msdn.microsoft.com/en-us/library/ie/ms536420%28v=vs.85%29.aspx, this method always returns null in IE11.

I suggest that you check the example "Module-script two-way interaction" in the manual, see the PDF file in the folder {Add-in Express}\Docs on your development PC. You can download the most recent version of the Developer's Guide at http://www.add-in-express.com/downloads/documentation.php.
