I am making an aspx page and need to link some css pages. From the root of the site collection the css pages are located in Style Library/CSS/files_here.css
My aspx page is located at SitePages/Page.aspx
<SharePoint:CSSRegistration ID="CSSReg5" name="Style Library/CSS/styles.css" After="corev4.css" runat="server"/>
The line I'm using above does not work, what is my flaw in my CSSReg? Before we moved this page to another site collection using a similar structure we had it working correctly.
