I am trying to push a button instance into an array with a string, and then I
want to be able to display the button with the string. Can this be done? On
the display page, all the data is dynamic and random, so I can't just hide the
buttons and then show them when I need them, since their position changes,
based on the user's answer.

Any help would be greatly appreciated.

hi,
i think this might help

myBtn = new Array(_root.btn1 , _root.btn2, _root.btn3, _root.btn4);
for (var i in myBtn)
{
myBtn._alpha = 50;
}

btn1, btn2, btn3,btn4 are buttons on the stage
bye

if you're pushing your instances using strings then you'll need to use bracket
notation to direct flash to resolve those strings into objects. for example,
if you have:

yourA=new Array("btn0","btn1");

then you can reference btn0 on the _root timeline by using:

_root[yourA[0]]
