 * I am developing a WordPress Widget Plugin that inserts as many as you want email
   input forms in a widget.
 * I am using the following code to validate email fields
 *     ```
       function validateForm(form) {
       var x = document.forms["twb_form"]["email"].value;
           var atpos = x.indexOf("@");
           var dotpos = x.lastIndexOf(".");
   
               if (x == null || x == "" || atpos< 1 || dotpos<atpos+2 || dotpos+2>=x.length) {
   
               document.getElementById('errorMSG').innerHTML = 'Please enter a valid email address';                   
   
               return false;
               }
       }
       ```
   
 * The problem is that validation error always display along the very first form
   on page regardless of other forms… This is because of the div #errorMSG
 * I know this can be solved using some kind of PHP tricks but I can’t figure it
   out.
 * Every form on the page is being applied a separate ID … widget-id-1, widget-id-
   2 and so on…
 * How can I associate each validation message with a widget-id ?
