InfoPath Dev

I have an InfoPath form with javascript code   function XDocument::OnLoad(eventObj) { XDocument.UI.Alert( Application.User.LoginName); // Write your code here //if(XDocument.IsNew) }   When I run it I get empty Alert. What's wrong??

I have in my InfoPath form a TextBox control. I want this TextBox to be Enable only to specifice users!!!!  I created a User role called "Office" and I defind the specific users to this role. (I have only 1 user role so this one is default) On the TextBox->Display tab -> Conditional Formatting -> I add the condition ...
