I wanted to conduct a simple experiment, where I update a dynamic text field on the click of a button. Well, it throws no errors, but it doesn’t work, and I can’t figure out where I went wrong.

```auto
import flash.events.MouseEvent;

var currentText:Number;

currentText = 100;

attackButton.addEventListener(MouseEvent.CLICK , onAttackClick);

 function onAttackClick(event:MouseEvent):void
{
    currentText = currentText-1;
    trace (currentText);
    updateDisplay();
}

function updateDisplay(){                                      
    healthText.text = String(currentText);
}

```

CurrentText is updated with each button click, but the text field goes from 100 to blank once I click the button.

I have searched the internet, but can’t find anything close to this.

Thanks,
