Navigate to your page and View->Source and you'll probably see this

 <SCRIPT LANGUAGE="VBScript">
 Sub Dial()

 end sub
 </SCRIPT>

So clicking your button does nothing. ASP executes first and the resulting
HTML is handed to the browser for display.

The basic answer is that you can't do what you're wanting using standard ASP
coding. There are technologies that let you run things on the server via
things in script but without knowing the ins and outs of what you want it is
hard to advise further.

What does this CallDial do?
