title: parseInt always returns NaN?
body: <p>long story short, i was trying to validate a phone field. ive added
  the <code>isNaN</code> and <code>parseInt</code> for checking the <code>" "</code> in the field but that said</p>
  
  <p>This below never validates to true..what am i missing?</p>
  
  <pre><code>if(isNaN(parseInt(phone))){
          error.text("Sorry but this phone field requires numbers only");
          return false;
      } else {
      return true;
  
      }
  </code></pre>
  
  <p>it always fails...it never reads true even when i enter a number in the field and submit.
  i always get the error mssg.</p>
  
  <p><strong><em>EDIT:</em></strong> I am testing input values from a form, <code>phone</code> is the name of the field.</p>
