Hello, i'm trying to delete a record but the problem is in my syntaxis this is my code:

<script language="JavaScript">
  function eliminar(){
    sw=0;
    for(var i=0; i<document.form1.radiobutton.length; i++){
       if (document.form1.radiobutton.checked){
        <%sqlborra='delete from RegistroPersonas where email='&document.form1.radiobutton.value
         set rsborra=conn.execute (sql)  ;
         alert("Record erased");
       sw=1;
                                           }
                                                           }
       if (sw==0){alert('Por favor seleccione un item a eliminar');}
                    }
</script>
