Link to root

hi
my file scructure is root/cars/makes

my html page is in the folder "makes" and in it i have a link that links to a <script>

randomlinks[0]="1.htm"



and I want it to link back to the root of the site eg root/1.htm
if i go
randomlinks[0]="../1.htm"

then it stays in "makes" and wont go to root

how do i tell this to look 1.htm in the root


thanks

Andrew
