You can easily tell if the problem is your report data or your report design by heading to the Preview tab and looking at the data in the right hand column. The XML there is what the report sees coming back from the data sources – if the XML is empty, the problem is your data.

Hey Kathy,

I have the same issue for mine, and the XML is not empty, but my preview is blank.

Then the problem is in your report design.

I have a transaction group to generate the data, but in the XML there are only the names for each columns, and no numbers.:disappointed_relieved:

You still have this problem?
