I don't know the CR object library, you'd have to look up what the Add method wants as parameter in the CR documentation, it obviously doesn't like "sqlparameter". Perhaps you can also use the intellisense option list or the Object Browser to see what parameter types is expects, but some libraries won't reveal it and only displays Object as type, in which case you have to rely on what the documentation says. Did you also try searching the web? I'm sure sending parameters to CR is a common issue.
