[Philosophaie]

Can you access a vbscript from a Javascript program.

<script type="text/vbscript">
function fn1()
     msgbox("Over the Limit")
end function
</script>
<script type="text/javascript">
     function month(){
            var m=Number(window.document.myform.mo.value);
            if (m>12){
                 "call fn1 to display msgbox;
                 "exit function month;
            }
     }
 </script>
