I've made a surveying system before from a preexisting web survey solution (LimeSurvey) where I've used filemaker tied in via ODBC to the MySQL results table, and processing the data into usable reports on the backend.
I think the Filemaker ESS to existing package idea saves on a heck of a lot of overhead, and of even more benefit, teaches you about web development as well.
Thanks for the info. From what you say, I assume you need to be more than just a FileMaker user to accomplish what you did?
What did you think of the example I linked to? Do you think that was a (pure) FileMaker solution?
looking at the page source of that, I'd imagine they are not using CWP as the processor. CWP is usually handled in PHP, but their form processor is JSP.
Yes, unfortunately my suggestion involves knowledge of LAMP (at least PHP and MySQL), but LimeSurvey is a pretty easy and free PHP solution to setup and host on a standard LAMP host, and on the filemaker side, it will teach you valuable ODBC/ESS techniques as well.
