Textfield and eventlisteners

Question

Hi guys, i fee im plauging this forum sometimes, this code lets a user input text and click a button which outputs it to a textfieldand also adds a number to another textfield. Another button removes this text and also subtracts the same number. It all works fine when there is text in the input field but when it is empty and you click the button that adds the text it still adds to the number.
[AS]
var textAdd01 : Number;
          textAdd01 = 3;
LBtextMenu.LBtxtSubmit.addEventListener(MouseEvent.MOUSE_UP, LBtypedChar);
function LBtypedChar(evt:MouseEvent):void
LBTxt.LBOutput.text = LBtextMenu.LBInput.text;
LBtextHotspot.gotoAndStop(2);
trace (LBTxt.LBOutput.text.length)
///----------------------Add Price---------------------------------------
LBtextMenu.LBtxtSubmit.addEventListener(MouseEvent.MOUSE_UP, LBtxtAddPrice);
function LBtxtAddPrice(evt:MouseEvent):void
priceOutput.text = String(textAdd01 + Number(priceOutput.text));
if (LBTxt.LBOutput.text.length >0){
          LBtextMenu.LBtxtSubmit.removeEventListener(MouseEvent.MOUSE_UP, LBtxtAddPrice);
          LBtextMenu.LBtxtRemove.addEventListener(MouseEvent.MOUSE_UP, LBtxtRemovePrice);
LBtextMenu.LBtxtRemove.addEventListener(MouseEvent.MOUSE_UP,LBtxtRemoveTxt);
function LBtxtRemoveTxt(e:MouseEvent)
  LBTxt.LBOutput.text = "";
          LBtextHotspot.gotoAndStop(1);
          LBtextMenu.LBtxtSubmit.addEventListener(MouseEvent.MOUSE_UP, LBtxtAddPrice);
          trace (LBTxt.LBOutput.text.length)
///----------------------Remove Price---------------------------------------
LBtextMenu.LBtxtRemove.addEventListener(MouseEvent.MOUSE_UP, LBtxtRemovePrice);
function LBtxtRemovePrice(evt:MouseEvent):void
priceOutput.text = String(Number(priceOutput.text) - textAdd01);
if (LBTxt.LBOutput.text.length ==0){
          LBtextMenu.LBtxtRemove.removeEventListener(MouseEvent.MOUSE_UP, LBtxtRemovePrice);

Thanks for any help in advance.

Thanks for reply Ned, yes everything is tracing as it should.   "LBtextMenu.LBtxtSubmit"  is the add button which takes the text from the inputfield "LBtextMenu.LBInput.text" outputs to the output field "LBTxt.LBOutput.text" and also adds the number "textAdd01" to "priceOutput.text".
"LBtextMenu.LBtxtRemove" is the remove button which removes the text from "LBTxt.LBOutput.text" and subtracts "textAdd01" from "priceOutput.text"
Dont know if that has made it clearer?
