when a viewer enters name into textbox and clicks OK button, the name will be displayed as WELCOME + NAME + TO MY WEBSITE on homepage. How do I do that?
Even if you have just enough ability with JavaScript to edit a script so it kind of does what you want, this should be good enough for you. They have the cookie setting and retrieving scripts on the page, and all you'd have to do is alter them slightly to fit your needs. Hope that helps!
