Help changing text in a textfield

Question

Hello, I am trying to create buttons that will replace the text in a text field. 
The text field is "Staff_Copy"
The buttons are "Staff_Saam_btn", "Staff_Nicolas_btn", "Staff_David_btn", and "Staff_Anthony_btn".
//Code in frame 1 of timeline
var Staff_Copy_Value:Number = 0;
var Saam_Copy:String = "This is the text for Saam's Bio";
var Nicolas_Copy:String = "This is the text for Nick's Bio";
var Anthony_Copy:String = "This is the text for Anthony's Bio";
var David_Copy:String = "This is the text for David's Bio";
//code in frame in which textfield first appears on stage
Staff_Saam_btn.onPress = function()    {
                Staff_Copy_Value = 4;
Staff_Nicolas_btn.onPress = function() {
                Staff_Copy_Value = 3;
Staff_David_btn.onPress = function()    {
                Staff_Copy_Value = 2;
Staff_Anthony_btn.onPress = function()              {
                Staff_Copy_Value = 1;
_root.onEnterFrame = function()             {
                if (Staff_Copy_Value == 4)          {
                                Staff_Copy.text = Saam_Copy;
                } else if (Staff_Copy_Value == 3)              {
                                Staff_Copy.text = Nicolas_Copy;
                } else if (Staff_Copy_Value == 2)              {
                                Staff_Copy.text = David_Copy;
                } else if (Staff_Copy_Value == 1)              {
                                Staff_Copy.text = Anthony_Copy;
This doesn't work.  Whatever the initial value of the variable "Staff_Copy_Value" is will determine the text in the field.  So if I use the value 0 as in the above, whatever is in the textfield on the stage shows.  If I use 1,2,3, or 4 then the text strings in the defined variables shows up.  What am I missing.  I am assuming it is has to do with the onEnterFrame command.  How do I make the movie keep checking the value of "Staff_Copy_Value"?
Thanks!

Hi,
try this:
//frame 1 of timeline
var pressing:Boolean = false;
var movement:Number = 0;
var Staff_Copy_Value:Number = 3;
//the text in the following strings are condensed.  The actual text takes
//more space than the text box will show.  Hence the need for scroll
//buttons.
var Saam_Copy:String = "This is the text for Saam's Bio";
var Nicolas_Copy:String = "This is the text for Nick's Bio";
var Anthony_Copy:String = "Condensed text for Anthony's Bio.";
var David_Copy:String = "This is the text for David's Bio";
//frame in which the textfield enters stage (25).
upButton_btn.onPress = function() {
    _root.pressing = true;
    _root.movement = -1;
upButton_btn.onRelease = function() {
     _root.pressing = false;
downButton_btn.onPress = function() {
     _root.pressing = true;
    _root.movement = 1;
downButton_btn.onRelease = function() {
     _root.pressing = false;
Staff_Saam_btn.onPress = function() {
     _root.Staff_Copy_Value = 4;
Staff_Nicolas_btn.onPress = function() {
     _root.Staff_Copy_Value = 3;
Staff_David_btn.onPress = function() {
     _root.Staff_Copy_Value = 2;
Staff_Anthony_btn.onPress = function() {
     _root.Staff_Copy_Value = 1;
_root.onEnterFrame = function() {
    if (Staff_Copy_Value == 4) {
         Staff_Copy.text = Saam_Copy;
    } else if (Staff_Copy_Value == 3) {
         Staff_Copy.text = Nicolas_Copy;
    } else if (Staff_Copy_Value == 2) {
        Staff_Copy.text = David_Copy;
    } else if (Staff_Copy_Value == 1) {
         Staff_Copy.text = Anthony_Copy;
    if (_root.pressing == true) {
          _root.Staff_Copy.scroll = _root.Staff_Copy.scroll + _root.movement;
