Easy Setup

The easiest way to set up the applet on your site is to start with the applet code in the sample HTML file found in VertTextScroller.zip. Use notepad and cut and paste the applet parameters from the sample HTML file into your HTML file. Then try it out, if it works, then customize it for your site. Please note, after you change the HTML file you must hit 'reload' on your browser to view the changes (sometimes you must close the browser and reopen it to see the changes).
Problems

If you just added the applet parameters to your HTML file and the applet doesn't load, try the following three steps:
  1. clear your browsers cache
  2. close your browser
  3. open your browser, and reload the page
Applet error: lineDefault value="null": 
If the applet displays the above error, this means the applet cannot find the required parameter lineDefault. View your HTML source in your browser (view > page source), the lineDefault parameter probably looks something like this: 
<param name=lineDefault>  NO space between the quotation marks.

It should have value="  " after it like this: 
<param name=lineDefaul value="   ">  At least ONE space between the quotation marks.

All the param tags MUST have a value. Some HTML generators like Microsoft Front Page and Claris Home Page have problems with value="" (no space betweem the quotes). These tags must be corrected, use notepad or your favorite text editor to fix the tags. 

Browser error: class VertTextScroller not found: 
If the applet doesn't start and your browser displays the error message above, make sure the file VertTextScroller.class is on your web server in the same directory as your HTML file. Also make sure it's spelled correctly, upper and lower case matter (spell it exactly like this: VertTextScroller.class).

If you can't fix the problem: 
Email me and include your sites URL and I'll take a look at it.
