getting issue in passing item value from modal dialog to main page item.

Hi , I am trying to pass item value from modal dialog to main page item.

I followed below things :

In the dialog page , I used Close Dialog process with the required item values listed as Items to Return

In the main Page , I created Dialog Closed dynamic action with a Set Value step of type Dialog Return Item.

but in dialog return item , i cannot see item of Dialog page . Please let me know what I would have been missing here.
