Great solution, but... another question

Like you say it works (with the correction) "." for which my thanks, but: if one my includes is a menu.php where there are links inside, how should these work from rootdirectory and from subdirectories. for rootfilelinks they now just say f.i. index.php, but when called from inside a subdirectories they are supposed to say /index.php. Any solutions for this one?? thanks Martin
