Textfields Try and Catch

Question

Hi All, just a quick question really...
Was wondering how I would go about checking user inputs into textfields?
For example if the user enters the number 12 and you're only allowed to enter numbers between 1-10 how could I send a pop up error message to say "You can only enter numbers between 1-10"
A way I thought about doing this was with a try and catch method, there could be another way of doing this, all other methods appreciated too.
function captureNumbers(evt:MouseEvent):void {
try{
numberSelect.push(Number(number1.text));
catch{
if (numberSelect > 10){
throw new Error("You must choose a number between 1 - 10");
button1.addEventListener( MouseEvent.MOUSE_UP, captureNumbers);
This is what ive got so far which doesn't seem to be working...
Thanks in advance

     void public readDB()
          Connection conn = null;
          PreparedStatement pstmt = null;
          ResultSet result = null;
          try {
               Class.forName("oracle.jdbc.driver.OracleDriver");
          catch (Exception e) { System.out.println("Can't load JDBC driver:" + e); return; }
               try{
               conn = DriverManager.getConnection
                   ("jdbc:oracle:thin:@username.domain.com:1521:adm2", "login", "pass");
               // @machineName:port:SID,   userid,  password d     
               stmt = conn.prepareStatement("select fname,lname,greeting from people where userid = ?");
                 stmt.setString(1,user);
                 result= stmt.executeQuery();
                 fname = result.getString(1);
                 lname = result.getString(2);
                 stmt.close();
               catch (Exception e) { System.out.println("Error with JDBC Connection:" + e); return;}
