Maintain Scroll Position on page in Web Config file

Could someone please explain exactly where the following statement should be added to the nopcommerce web config file?

<pages maintainScrollPositionOnPostBack="true" />

I have added it to the  </appSettings><system.web> section but I get a config error when I run it.  If I comment it out nopcommerce runs fine.

The error is:

HTTP Error 500.19 - Internal Server Error

Module  IIS Web Core
Notification  BeginRequest
Handler  Not yet determined
Error Code  0x800700b7
Config Error  Config section 'system.web/pages' already defined. Sections must only appear once per config file. See the help topic <location> for exceptions
Config File  \\?\C:\inetpub\wwwroot\ESCPDublin\NopCommerceStore\web.config

61:     </siteMap>
62:     <pages theme="DarkOrange" validateRequest="false" controlRenderingCompatibilityVersion="3.5"  clientIDMode="AutoID">
63:       <namespaces>

Thank You.

See the underlined message above.

Just find an existing <pages> section and add 'maintainScrollPositionOnPostBack' element to it

@a.m:  Thanks a lot.  That worked great.  It was not clear that all I had to do is append it to the existing <page "xxxx"> string below:

<pages theme="DarkOrange" validateRequest="false" controlRenderingCompatibilityVersion="3.5"  clientIDMode="AutoID" maintainScrollPositionOnPostBack="true">


Now, does anyone know of a similar command that will work on the Firefox browser as well?  This command only seems to work only on I.E...
