Why not just set an an instance variable(some people say global) like: mx.core.Application.application._NextButtonViewIndex = event.target.data;
On Click you could then do: myViewstack.selectedIndex = _NextButtonViewIndex; You are using a ViewStack, I hope?

I think if I were making a wizard, I would use a different mxml component for each wizard screen. And I would store the input from each wizard screen in the parent application. Hope something here was useful to you, though I doubt it : ) ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of face7hill Sent: Wednesday, October 05, 2005 3:22 PM To: [email protected] Subject: [flexcoders] Pass data from child component to parent in wizard app Hello All, I have a wizard type app called "main.mxml" with three children ("screen1", "screen2" and "screen3"). I have a button in main.mxml called "nextButton". Inside screen1.mxml are a couple of radio buttons that a user can select. How do I get the selected radio button (in the child component) to broadcast to the nextButton (in the parent app) where it should point to? For example, in the code below, on screen1.mxml, I have a function: //this function is fired when a user selects a radio button function buttonClicked( event : Object ) : Void { //this works //sets the status label in the parent app mx.core.Application.application.setStatusLabel (event.target.data); //this does not work //trying to set where nextButton (in the parent app) will point to when the nextButton is clicked mx.core.Application.application.nextButton.click = mx.core.Application.application.goToScreenName(event.target.data); } Am I approaching this the wrong way? Any suggestions? I am essentially trying to create a wizard like application where the flow from screen to screen will be based on the user's input on each screen, so the nextButton.click in the parent app will be dynamically assigned.
