Call procedure with commandbutton in webpage

[susan]

Hi,

I'm using Accrss 2003. I try to build a GUI using the Webpage-option in
Access. Now I want to call a procedure by placing a CommandButton on the
webpage. Doing so I find the following in thr Microsoft Script Editor

<SCRIPT language=vbscript event=onclick for=Knop0>
<!--

-->
</SCRIPT>

What do I have to adjust in the webpage-code to call the following:

Public Function BTV()
MsgBox "Here I am!"
' and lines and lines of code will follow ...
End Function


Hope anyona can help.

Thanks,

susan
