I keep track of music chart data. I have input data since 1/1/2016. I have now created a summery report that sorts the data by song title. In the sub-sumery part of the layout, I have the song title, singer, and the peak chart position of the song (using a summery field). For this example, I have the chart history of "Country Nation" by Brad Paisley. I can clearly see in the sub-summery line the song reached #18. I want to put in the sub summery line the date that the song first reached #18. I can go down the chart history and see it reached #18 on 2/13/2016, but I want that date to appear in the highlighted sub-summery line beside the peak position. How do I do that?
