I'm working on site where the navigation loads new content into the top and bottom frames. I found this script at 3schools and modified it to work with an href tag rather than a button. If that were all I needed, it'd all be good cuz it works just fine. But I need to take it a step further and use the changeurl() function on more than one href tag. I tried defining more than one function like this: changeurl(category1) then define the frames and sources for each category, but it's not working. How can I have more than one changeurl()?
