Message Box

What do you mean with a "message box", something like can be done with javascript ?

Javascript or VBScript will do .
cos I don't want to navigate to another page to show the error message .
If I do this, then When I navigate back, all my textfield will be empty and I need
to type in all over again just for a mistake I made earlier .

in javascript:

<script>
alert("this is a message")
</script>

Is this what you mean ?

Yes,

But How am I going to call it in the ASP Script ?
Let say

if index < 1 then
   ' Need to call the message box here
end if

<Script Language = "JavaScript">
alert("dffdg")
</Script>

er............ For your information,
my asp script is run at server. So if I use your codes,
it gives an error message nested Script .

Any other idea ?

Ah, I see, you use:

<SCRIPT RUNAT=SERVER>

</SCRIPT>

as your ASP scripting tags. Yep, then that is what happens.

Change those tags to:
<% and %>
And the problem is gone.

or do it like this:


.
..
If index < 1 Then
</SCRIPT>

<script>
 alert("this is a message")
</script>

<SCRIPT RUNAT=SERVER>
End If
..
.


You have to write the javascript code outside of the <SCRIPT RUNAT=SERVER> tags.
With <% %> you can write javascript code
