Let me know if you need any assistance.

Having the errors Page: Initialise Stage: Stage1 Type: Error Action: Validate Description: Compiler error at line 305: 'System.Array' does not contain a definition for 'Contains' and no extension method 'Contains' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)
