I have this simple JS and works about 90% ok.

I need to include a part taht will validate a radio group to make sure an option has been selected.



<script language="JavaScript" type="text/JavaScript">


function trim(value) {
   var temp = value;
   var obj = /^(\s*)([\W\w]*)(\b\s*$)/;
   if (obj.test(temp)) { temp = temp.replace(obj, '$2'); }
   var obj = / +/g;
   temp = temp.replace(obj, " ");
   if (temp == " ") { temp = ""; }
   return temp;
}

function validateEmail(fieldValue) {
     return (/^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$/).test(fieldValue);
}


function Validate() {
              document.forma.nombre.value=trim(document.forma.nombre.value)
              if (document.forma.nombre.value.length == 0) {
               alert("Falta Nombre.")
                return(false)               }      

               document.forma.telefono.value=trim(document.forma.telefono.value)
               if (document.forma.telefono.value.length == 0) {
                alert("Falta Telefono.")
                return(false)                  }

        
              if (!validateEmail(document.forma.email.value)) {
           alert("La dirección de correo electrónico no es valida.");
           return false;
               }      




        return(true)
       


}

somn like this should work:

function Validate() {
              document.forma.nombre.value=trim(document.forma.nombre.value)
              if (document.forma.nombre.value.length == 0) {
               alert("Falta Nombre.")
                return(false)              }    

               document.forma.telefono.value=trim(document.forma.telefono.value)
               if (document.forma.telefono.value.length == 0) {
                alert("Falta Telefono.")
                return(false)               }

       
            if (!validateEmail(document.forma.email.value)) {
          alert("La dirección de correo electrónico no es valida.");
          return false;
              }    


         var myOption = -1;
         for (i=document.forma.radioGroupName.length-1; i > -1; i--) {
           if (document.forma.radioGroupName[i].checked) {
             myOption = i;
           }
         }
         if (myOption == -1) {
            alert("You must select a radio button");
            return (false);
         }

        return(true)
       


}
