BrowserUk, Thanks for the pointer. Now looks like the value of $text can successfully be passed to the parent at some point. But somehow this $text is not dynamically changing. I'm expecting $text can be dynamically displayed and that's why I created two infinite loops in both child and parent.

Anyway, thanks again :)
