User Function Library for Crystal with Vantage Viewer!

I want to create UFL's for some of our Crystal based reports. The
problem I have is the viewer Vantage uses. Besides it's mix match of
dlls and lack of features it doesn't seem to like any of my custom
functions. The U2Lcom.dll Crystal uses doesn't even seem to be in
the Vantage dll directory. So I called in and they sent me to Custom
Programming. Custom programming emailed me an said UFL's work, but I
haven't been able to get any additional info from them.

I am holding on to the hope that custom programming isn't full of it,
and that someone else might know what I have to do to get my custom
functions to work.

Thanks,
