It's supposed to work very well, as long as you're working with ADP's. The usual (and true) message when working with mdb's are "2593 This feature is not available in an MDB".
Usually, with a tad more info (for instance the exact errormessage, what technology you're using (adp/mdb), somewhat more of the code...) it's easier to find out what's going on.
If you haven't read faq181-2886, yet, please do.
