I had a report that seemed to be working properly, but I added an extra dataset so that I could use the information in the query I wrote to pass into a custom code function I wrote. However, when I click on the expression to make a change no fields are coming up and I see the message that this report item is not linked to a dataset. This report has no table its just a blank report made of expressions and fields. I can't figure out how to link my expression to a dataset. Can someone help me out.
Thanks in advance
