>The "text" I am trying hide is on a html page which is part of our help file. I want to only show one of the paragraphs if a file called demo.txt is in the current folder. I want to use the same html page for our demo and normal application, but hide part of the page if it's a demo program.

John,

This sounds like something that would be suited for some DHTML in your page that would dynamically make that section visible or invisible.

If you do a Google search on "DHTML hide content" you should be able to find plenty of examples that show how to accomplish this.

Laterness,
Jon
