TreeView HoverStyle

Hi,

I am using Expression Web 2 to develop my website.

I am trying to set the HoverStyle for my TreeView on my downloads.aspx page.
I get error
"Using TreeView.HoverStyle requires Page.Header to be non-null (e.g. <head
runat="server" />).
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information about
the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Using
TreeView.HoverStyle requires Page.Header to be non-null (e.g. <head
runat="server" />)."

I have used treeview and don't get error if I don't use the HoverStyle.
What do I need to add and why?

My page details are as follows:

Hi Morris,

page.
> I get error

To use HoverNodeStyle we must include a <head> element with a
runat="server" attribute. For example you can use this header to replace
your current one:

<head runat="server" id="head">

For more details please refer to:
