Cannot find control on my page

OK, I added the following in my aspx page:

...
<p runat="server" id="paragraph1">some text is here....</p>
...

My codebehind (.cs) has this trying to reference this tag.  Wehave thi working on other projects like this, same code.  But for some reason I get "C:\directorywhatever\mypage.aspx.cs(68): The type or namespace name 'paragraph1' could not be found (are you missing a using directive or an assembly reference?)"  

There is definitely no missing .dll, this is simply referencing an html server-side control now that I put runat="server" id="paragraph1" in that tag

I'm using VS 2003 to build, what could it be?  Why isn't it finding that server tag?

I have othe rpages in thi sproject, aspx pages that are setup like this, and after adding that paragraph tag in, the code-behind for those other pages can see it fine.  It's just on 2 of the pages that cannot find it like this, wondering if I need to add a reference somwhere to make VS 2003 aware of the control?

In the code behind file you'll need to add a reference to that new control.  Other controls are referenced at the top of the code behind, usually automatically when you use VS2003 designer to add them to your page.  If you edit the HTML directly, you just need to add the control declaration yourself.

I don't know the C# equivalent off the top of my head, but in VB it looks like this:

"Protected WithEvents paragraph1 as LiteralControl"

have you switched to design view rather than html since you added it? I have found that VS Express editions are not aware of new controls until I have switched to design view. Probably not relavent but thought I would mention it just in case as a possibility...

The only thing to watch out for in VS2003 is when you switch to Design view it can really mess up your HTML. I'd manually add the reference to code behind page.
