can i do an interaction that would create an xml output file?

lectora can email test results as xml, but that's not going to get the data where you need it to go. for instance, you could create a 'test', which contains radio buttons your user has to tick off. lectora emails results in xml format. but, no worky for you in this case.

how's your flash skills? methinks that's the road you're going to have to take.

keep in mind i could be totally wrong.

btw...is this course going to live in an LMS?
