I am using this script which allows people to add links to a page and stores them in a cookie. I am redesigning the site and need to limit the amount of links which display to 5 or less. and/or restrict the amount of future entries to 5.

If needed, you can see it live at www.wirejump.com/dj.htm

thanks for any help in advance.

Well glancing at the code I see a max variable. Did you try changing that?
