Error when I add meta to header.html

When I add the following Meta to the headers.html I get this error, is there anything that I should be doing differently to include the stylesheet?

<link rel="sStylesheet" href="libs/typicons.font/typicons.css">;

Error: Failed to load template /pd/pagetemplates/headers.htm?tc=52070198 in templates/page.htm on line 7
