Error using more than one dataset

Hi,

I have a problem using more than one dataset to create my report. I wish to use data from one stored procedure to create the values for a combobox, that I use as input to another stored procedure.

When I create more than one dataset and set up my report parameters to use one of them to create comboboxes, I get the following error, when I want to see the preview:

An error occured during local report processing.

The definition of the report '/StockInTrade' is invalid.

The data set name is missing in the data region 'DataSetName'

The report worked just fine when I used hardcodede values for my combobox. The error occurs as soon as I define more than one dataset (meaning it fails even before I try to use the second dataset as report parameter values).

Does anyone know what I am doing wrong?

The error occured because I had a table without a dataset attached!
