text input validation for numeric check

Question

I am seeing a strange issue in flex. I need to reset all text input fields to 0 once the user submits the values to be calculated. In the method

     private function calculate():void {
       resetToZero();
       var num:Number = parseFloat(s21.text);    
      }  


     private function resetToZero():void {
      //multiple if statements.... existing here..    
     if(s2l.text.length ==0);
 {  
    Alert.show("length is:" + s2l.text.length);
    s2l.text="0";
 }
}

When I am running the program I am getting the alert - length is 1. How is that it when length is 1 it is entering the if statement?. The behavior is really confusing and need some light on this. Is there any other way to achieve the above functionality?

Its because of IF statement, which is terminated

if(s2l.text.length ==0);

Remove ; from end as

if(s2l.text.length==0)

Hopes that helps
