hi,

the next script works perfectly in explorer but doesn't work ik firefox,
It is supposed to change bgcolor of the page depending on wich menu the page belongs to.
REPLACE_BY_MENU is replaced by the correct number.
So the error should lie in document.bgcolor ?
you can see the result at www.bouworde.be (dutch speaking site)
