Server Side form tag

Im a novice to asp.net i have a xhtml template that i am trying to add a dropdown list using visual studio 2005. However whenever i try and do this i get the following error: "A page can have only one server-side Form tag. " can anyone help please!!!! very frustrated!!!

 

Are you using a Master Page and a Content Page with the form element in both?

 

You can have lots of html forms, but only one <form ... runat="server"> tag.

 

i think u have two "forms" or something outside the tag form that run on server

 

does that mean i can put it within the run at server tag? because when i drag and drop a form tag it automaticaly inserts a runat server tag. is there anyway i can over come this?
