Im writing a project in C# and I'm working with the crystal plugin from VS2010.
I've created a report, but it has some odd problems:

1. I placed the same field twice in the details section. when I look at the report preview it all looks fine, but when i run the report from the C# program i can only see one of those fields.

2. I made a formula field that gives the string "yes" if a certain boolean field in the DB is true, and false otherwise. again, it looks fine in preview mode but I can't see it in the program. If i put that formula field in the group header and not the the details section I can see it fine in the program.

Do you have any idea what can be the problem?
Thanks in advance.
