Hi Phil and welcome to our community
The Captivate output files are a bit like a house of cards.
All elements are critical. Here's how they pan out.
You upload all the files to your server. Normally in the same
location.
You point your user to the HTML file.
User clicks the link pointing to the HTML file and it loads
up into the browser.
The HTML file looks for the standard.js file. Assuming it is
found, more code is added to the HTML file.
The MainMovie_skin.SWF is then loaded into the browser
window.
Internally, the MainMovie_skin.SWF knows to look for the
MainMovie.SWF and it loads up.
As each slide pointing to a .FLV is encountered, the .FLV is
loaded at that time and plays.
As for embedding into an existing page, you will need to sift
through the code for the Captivate created HTML file for clues. Are
you using a Web Development tool such as Dreamweaver, FrontPage or
Expression Web designer?
