Trying to create an input dialog box, that will halt execution

Question

I am trying to get a pop up dialog box to appear where the user will enter their name, after clicking OK or Cancel, i would like the code to continue executing.  For example when i use the Alert.show("1");Alert.show("2");Alert.show("3");  it appears as 3,2,1. Is it possible to fire one alter at a time AFTER the user has clicked Ok.
Back to the originial question.
I am setting up a Pop up menu
var ret:String;
var Dialog:SimpleTitleWindowExample =SimpleTitleWindowExample(PopUpManager.createPopUp( this, SimpleTitleWindowExample , true));
ret = Dialog.Input      //where input is just a public text for example
return ret;
^returns null.
I was hoping it would wait until  it was closed to continue. I thought it would by setting the modal = true
Essentially I'm asking is there a way to halt execution until the user inputs some text? Doesn't have to utilize the PopUpManager.
Please help. I've spent 4 hours trying to tackle this.  I even tried to do a DoEvent (Visual Studio) type loop until the button was clicked or variable was no longer blank.

I think you may alternately be able to listen for the removedFromStage event and react to that. In any case, you need some way of reacting to SampleTitleWindow closing (via an event listener), and only then trigger the next pop-up.
