I am totally new to jquery and did manage to design a form and check fields on values (with a little help;)). Now i also have 2 radio button options, and at least 1 need to be checked. So i would like to validate this too before the form will be sent.

Here is my validation now, without the radio funtion:

2. //ckeck if inputs aren't empty
3. var emailPattern = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;  
4.         var fields = $('#first_step input[type=text]');
5.         var error = 0;
6.         fields.each(function(){
7.             var value = $(this).val();
8.               if( value.length<1 || value==field_values[$(this).attr('id')] || ( $(this).attr('id')=='email' && !emailPattern.test(value) ) ) {
9.                 $(this).addClass('error');
10.                                 
11.                 error++;
12.             } else {
13.                 $(this).addClass('valid');
14.             }
15.         });        
16.         
17.         if(!error) {

Really appreciate your help!

greets.
