Hello I have a "menu" page in a iFrame like:
<div class="navBar"><a href="#l" target="content">First Page</a> | <a href="#">Next page</a> | <a href="#">Back page</a> | <a href="#" target="content">Last page</a> | <a href="pdf/arm001.pdf?print_pages=true" target="content">Print Page</a></div>
How can I write a menu in my top Iframe like:

FIRST PAGE | NEXT PAGE | BACK PAGE | LAST PAGE

that can open the pages in the "content" iFrame?
