Hi Claude,
The error means that your code have imported two namespaces, namely "ChartDirector" and "System.Data". Both of the namespaces have a class called "DataSet". In your code, you just specify DataSet, without the namespace. So the compiler cannot know if you are referring to "ChartDirector.DataSet" or "System.Data.DataSet".
To solve the problem, if you are referring to ChartDirector.DataSet, please use ChartDirector.DataSet (instead of just DataSet). if you are referring to System.Data.DataSet, please use System.Data.DataSet (instead of just DataSet).
Hope this can help.
