Well, my first question is, "Does the report have parameters?" It appears so from the error message. Gotta write the code to populate the parameters before doing the export.

I see. Crystal Reports doesn't share data between the report object and the viewer. You have to either set all properties using the report object or all properties using the viewer object. But not both. If you try to use both (as you are doing) CR will default to using the properties of the report object and ignore any settings of the viewer object. That's why it doesn't see the parameter values you added.

It's best to stick with the report object because it is more robust. The viewer object only has minimal properties available.

Also, your code is loading a new report document instead of working with the report that's already in your viewer.  That's why you are seen the parameter error - you may have set the parameters in the viewer, but you haven't set them for this new report document object.  It doesn't matter if they're both loading the same report file, they're two completely separate objects at this point and you have to set all of the properties for both.
