Use the IFunction.Parameters property to specify required and optional parameters and their types. This array of parameter information will define the function signature. When a custom function is used in a worksheet formula, the parameters will be checked for compliance with the array of ParameterInfo objects accessible via the IFunction.Parameters property. When inconsistencies are found, a warning message box is shown.

Parameters should match the ParameterInfo in type and attributes. In addition, all required parameters should come first, followed by optional parameters. ParameterInfo corresponding the optional unlimited number of parameters should be the final item in the array.
