Crystal Reports UFPrefixFunctions

Message

   Hi,

I've created a UFL using C# (Visual Studio 2008)  and have successfully 
implemented it in some reports using Crystal Reports 2008.  What I 
haven't been able to do is to prevent the prefixes from showing in the 
Formula Editor.  I read that if you use UFPrefixFunctions and set it to 
false, that should do it.  I've tried 3 ways (below) but none of them 
works.

Has anybody been able to use UFPrefixFunctions successfully?   And if so, what am I doing wrong?

Thanks in advance.

Ron
