Script to make sure at least one option is ticked in a submittal form

I am at an end to add a code to check my form to be sure that one of the options on my form are ticked. I have been researching EE with no success. Please forward needed code to check the option buttons. I am very new to working with submittal forms.
Thanks

Robert

If you want to make sure one is checked... you can use this validation code:

function ValidateForm(form)
{
   if(IsEmpty(form.firstname)) 
   { 
      alert('Please enter your First Name!') 
           return false; 	  
   } 
   
   if (!isValidEmail(form.email.value)) 
   { 
      alert('Please enter correct email address!') 
         return false; 
      } 
   if(IsEmpty(form.comments)) 
   { 
      alert('Please enter your comments!') 
     // form.account_number.focus(); 
      return false; 	  
   }  
 
   var valchecked = false;
   for( i = 0; i < document.myform.InfoRequested.length; i++ )
   {
       if( document.myform.mygroup[i].checked == true )
       {
          valchecked = true;
          break;
       }
   }
   if(!valchecked) 
   { 
      alert('Please check one of the radio buttons!');
      return false; 	  
   }  
   
   return true;
 }
