Run Time Problems. The expression contains undefined function call MyUserFunction().
Environment

Description
An error with red message 'The expression contains undefined function call MyUserFunction().' occurs in the report.
Solution
There are three cases in which this error message occurs:
- The function name is typed in manually in the Expression, without building the class library, and it does not exist yet.
- Using the function with incorrect number/type of parameters. The passed fields must match the function signature.
- The field specified in the function is null. Make sure such cases are handled in the user function.
