I created a movie in Flash Firestarter - it works great, but I would like to use it on the main page of a website that I created in Visual Site Designer. I tried using the Insert HTML object, but it doesn't work. Is there a trick? Or would I have to edit the page afterwards in the HTML editor?

check this tutorial out for Firestarter, and if you still need assistance please come back.

Good luck, Joanne,
It can be done, quite easily.

A few caveats:
1 In my movie I found "where to go when the movie ends" and set it to http://www.mypage.com/realhomepage.html/. If it is set to www.mypage.com the movie will loop for ever. Note that you can set up a hot spot over a "Skip the intro" text box, and send it to the same page (or someplace else).
2 I set up a separate page (I called it Flash) that contained only the html object with the firestarter code. I checked the 'home page' box on this page
3 I copied all the stuff per the video and Firestarter instructions. Make sure everything is in the mypage_vnu folder.
4 In VSD I did a preview to test it out. Note that the preview will jump to the real, published site upon termination.
5 The fun comes when you want to change your movie and incorporate those changes online. If you figure out a slick way to do this, please post it here.

PS Do not click on the 'mypage' links - they are fake but do point to a real site (Huh?) Heck, you know what I mean...
