Hi, I have a dynamic list of radio button that the user can select from.  
To check to see which one is selected, I do the following.

   var radioObject = form.tableItem;
   var valID	   = null;

   // find which item is checked
   for (var i=0; i<radioObject.length; i++)
   {
     if(radioObject[i].checked)
     {
       valID = radioObject[i].id;
       break;
     }
   }

This works great, except when there is only one radio button....  Then 
radioObject.length is NULL!
How do I handle the case when there is only one radio button.  

Thanks in advance.
