I'm probably doing this wrong in the first place, so feel free to point me to the video or class that teaches how to do this properly.
Here's the situation:
We are an Army Band with lots of performing groups and musicians who change between groups constantly. We make 'Job Sheets' to identify which musicians are performing on which performance. We also have lots of turnover in the Band since the Army moves us every 3 years. I want a Report that shows the current list of musicians in our organization, arranged by instrument, that will auto-update as people come and go. I created a Report that does this by making individual Queries to isolate the different instruments, then individual Reports based on those Instrument Queries (15 Queries, 15 Reports). Then, on my big Report, I dragged and dropped all those Instrument Reports and resized them so they all fit. However, as you can see in the pictures, there is some space on the form where I can't put that box - it jumps from overlapping the one above to overlapping the one below.

Here is the question - is there a better way to manipulate this report(s) and/or is there a better way to do this in general? Any advice or topics to learn about would be appreciated.
