Include file in asp.net

[Lavdim]

Hi!

I have a asp:menu that I want to show on every of my others forms.. But I get the error message "A page can have only one server-side Form tag. Thats because the asp:menu must have runat="server" and it must be under a form that has the tag runat="server"

And because of the form where I want to include the menu also has runat="server" I get the error message.

Is there anyone that can help me??? Pleeeassse!!
