How to assign {} to session variables

[GauravTMG1]

We are trying to assign value to a session variable like below:-

MenuSelected{IDCards}

But Cisco call studio is throwing an error : 

Configuration error: The value of the Session data variable 'IVRState' contains substitution errors: "{IDCards}": Invalid Key: IDCards

If you want it as session , here is how :

{Data.Session.IDCards}

If you want it as element :

{Data.Element.IDCards}
