thanks! the HTML error message i am getting simply says:
an error has occurred on the script in this page

and then:
object doesn't support this property or method.

i'm wondering, the page was written in javascript - is it possible that media lab won't support this format?

as for the continue button issue... the html page has a submit button on it, so is there anyway that this could replace the continue button? after they hit the submit button they are led to a second html page that gives them a "wait for feedback message" which is displayed for 30 seconds, after that time has elapsed they are automatically taken to a page that provides false feedback. at this point - once they have read the false feedback - a continue button would be suitable. is there any way to tell medialab that the continue button should only appear at that point? let me know if my question still isn't clear enough!

thanks again!
looking forward to your reply,
Sonia
