Exactly how you do this depends on which button states your NavBar includes, whether your web page already exists and which software you use for editing your web pages.
This covers simple text editors where you directly edit the HTML.

What's wrong with the NavBar?
The button graphics don't appear
Your NavBar looks like this:
The reason is that the browser cannot find the GIF or JPEG files for the button graphics. You need to copy them into the same folder as the web page. If the graphics are in a different folder to the web page, you need to edit the IMG tags to point to the graphics folder.
Remember to upload the graphics when you upload the web page to your server.
I get a Runtime error message when I view the web page
NavBars with either the Mouse Over or Selected states have two blocks of HTML code. One block controls displaying the button graphics. The other block is in JavaScript and controls switching between button states. The Runtime error means the JavaScript block is missing or in the wrong place. Use the editor options above to check you copied the JavaScript to the correct place. FrontPage users: when you open the page created by Xara Xtreme, you need to select everything on the page. Selecting just the NavBars graphics doesn't copy the JavaScript.
