adding Rating box to existing page

Hi, I've a page in this view:
http://demo.nopcommerce.com/Category/50-desktops.aspx

Under the Product name (Compaq Presario SR1519X Pentium 4 Desktop PC with CDRW), I'd like to add the Rating box under it , like this:

Compaq Presario SR1519X Pentium 4 Desktop PC with CDRW
*****
Current rating is 0.00. Total votes 0.

Is it possible, if so, could someone please show me how to do this.  Or just let me know which files i need to modify.

Greatly appreciate,

suggest you start with
modules/ProductInfo.ascx
and
templates/product/VariantsInGrid.ascx

hi, sorry, i'm a newbie at these stuffs :-)  Could you please give more info.?  thanks alot

i get error when trying this:

in productinfo.ascx, i added this line (took it from VariantsInGrid.ascx) to the top of the page (after the CodeBehind line):

    

<%@ Register TagPrefix="nopCommerce" TagName="ProductRating" Src="~/Modules/ProductRating.ascx" %>

then after the product name, i added this:

<h3 class="productname"><asp:Literal ID="lProductName" runat="server" /> </h3>
<nopCommerce:ProductRating ID="ctrlProductRating" runat="server"></nopCommerce:ProductRating>

Error:

Parser Error Message: Unknown server tag 'nopCommerce:ProductRating'.

I'm curious if a solution was ever found to this error, as I'm having same error.
I wrote a new control, built the project (no errors), uploaded the proj DLL and the control's code
poof - Parser Error Message: Unknown server tag <blah bah bah>
